Brooding in Poultry – Everything You Need to Know!

If you are raising baby chicks this year or in the near future, then you definitely need to know the ins and outs about brooding in poultry!

There’s nothing more exciting than having baby chicks around in the spring. They don’t need much, but making sure that they have the proper set up and care is essential to their health and well-being.

I’ve been perfecting my method for brooding in poultry for years and can’t wait to share all of my best tips with you.

Let’s jump in!

What Is Brooding?

Brooding is the process of creating an environment to raise your baby chicks in that is as close to their natural environment (mama hen) as possible. 

This created space is called the brooder and typically includes a container or box, bedding, heat, light, food, water and grit. Chicks will need to live in this space until they are fully feathered and large enough to graduate to the big coop.

Types of Brooding in Poultry

Natural Brooding

Natural brooding is when mama hen takes care of her own chicks. Mama hen will keep her chicks warm with her own body heat and teach them how to scratch for food. Natural brooding is truly special experience to watch, and much easier for you since mama hen takes care of everything,

Artificial Brooding

Artificial brooding is when we simulate what mama hen does by providing shelter, warmth, food and water. There are many different products and strategies out there, so it can be hard to know what’s the best approach to use. 

I’ve been brooding chicks for many years and have perfected the process. I am confident that my method will help you be successful, too! 

Supplies for Successfully Brooding in Poultry

Brooder Container

Finding a suitable container is the first step of the process of brooding in poultry. A container is important to not only keep chicks from wandering away from their food and heat source, but to keep predators out (I’m looking at you, barn cats!)

This container could be as basic as a cardboard box or as elaborate as a custom-made wooden structure or purchased battery brooder that can be used year after year. 

Simple brooder set up in a plastic tub


The first step in choosing a brooding container is deciding how big it needs to be. A general rule of thumb is to provide the following amount of floor space based on the age of the chicks:

  • 0-1 week: 6 square inches of floor space per chick
  • 2-11 weeks: 2.5 square feet of floor space per chick
  • 12-20 weeks: 5 square feet of floor space per chick
  • 21+ weeks: 7.5 square feet of floor space per chick

Therefore, if you have 10 baby chicks, you’ll need to start with a minimum of 60 square inches (10” x 6” space) and work up to 50 square feet (5’ x 10’ space) by the time they are 12 weeks old. Just make sure that the space isn’t too large when the chicks are young, otherwise they can get lost from the heater and freeze.

To accommodate their increasing need for space, you can simply plan to upgrade their box size as they grow. Another alternative is starting with a large brooding space, but block off a smaller section to confine them to when they are small and gradually expand the space as they grow.


Now that you know how much space you need, it’s time to decide what kind of brooder design you want to use. 

Cardboard Box or Plastic Storage Tub

Using a cardboard box or plastic tub is the simplest and most common option for a brooder container. These tend to be a great size for the backyard chicken keeper or homesteader, plus these materials are something that most everyone already has on hand. 

Plastic storage tubs are great because they wash up easily to use year after year, however, they are fairly limited in size. I typically start my chicks in a plastic tub in the house for the first week (see above photo for my set up), and then move them to a bigger cardboard box in the garage after that.

Cardboard boxes are an excellent choice because they come in so many sizes and are easy to come by. You could start in a basic small 11”x17” moving box and graduate to an appliance size box. Swing by Home Depot or Lowes sometime and see what they have laying around!

The ideas don’t stop here either! You could use a stock tank, a dog kennel, empty fish tank, tent or even a kiddie pool! Look around your house; I’m sure you’ll find something that will work laying around.

Brooding TIP: If you have potential predators around, you will need to craft some sort of a breathable cover to lay on top of your box. It doesn’t need to be fancy! I just use a screen door and secure it in place. Easy peasy!

DIY Brooder

If you’re getting serious about brooding in poultry and plan to do it year after year, you may want to invest in making your own brooder box that has more functionality than a basic cardboard box.

One option is to build a brooder into the wall of your chicken coop, which is what we’ve done on our homestead. It’s a great way to utilize free wall space and get your chickens accustomed to each other! I also find that accessing the chicks from the side, rather than coming in from the top of a box, is less stressful for them (think aerial predators, like hawks!).

Battery Brooder

Purchased battery brooders tend to be the best option for those that are operating at a large scale. They can be pricey, but super nice to use! Check out this amazing battery brooder from Tractor Supply.

Brooder Flooring

Now that we have our container figured out, we need to have a game plan to handle all of the poop (yep, chicks poop pretty much non-stop!) and provide a warm, dry environment. 

Absorbent Bedding

Using some form of absorbent bedding is the most common option for brooder flooring. You can typically find compressed bags of pine shavings or chopped straw at your local feed store; both of these work great! 

Other options include crushed corn cobs, peat moss, crushed cane, shredded dried leaves, finely shredded paper, vermiculite and coarse sand. You can get creative, just make sure that it isn’t super fine or resembles food.

Brooding Tip #1: Your chicks will be pooping pretty much non-stop, so make sure to stir the bedding up daily to keep it loose and absorbent. You can add a new layer of bedding on top to keep it fresh, too! When the bedding gets fully soiled (or wet from a spilled waterer), remove it all and start with a new layer. Avoid wet bedding because this can lead to mold growth and brooder pneumonia.

Brooding Tip #2: For the first week, I recommend using an old bath towel or paper towels as your flooring. This is because the baby chicks are still learning what is food and what isn’t and can often end up eating the bedding materials. 

Wire Flooring

You’ll often see wire flooring with a droppings tray below as an option in DIY brooders or battery brooders. They have some benefits such as easy clean up and less risk of brooder pneumonia. However, there are some disadvantages as well such as an increased risk of cannibalism and coccidiosis.

Heat in the Brooder

Providing a heat source is absolutely necessary because the fluffy down on baby chicks are insufficient to keep them warm. They will need a heat source until they are fully feathered and able to maintain their own body temperature.

Chicks have different heat requirements as they grow. They need their space to be 95 degrees at the beginning, then reduced by 5 degrees every week. This process continues until room temperature is reached, or the chicks are fully feathered; whichever one comes first!

Watching your chicks behavior is the best way to determine if they are too warm or too cold.

  • Happy chicks will be evenly spaced out and happily cheeping or sleeping comfortably.
  • Cold chicks will be huddled together under the heat source and chirping loudly. If they are cold enough, they will pile on top of each other, smothering the ones on the bottom.
  • Hot chicks will move away from the heat source and pant. If temperatures reach 117 degrees, it can be lethal.

Making sure that your chicks are the right temperature (and without burning down the house in the process) is the most stressful part of brooding, in my opinion. Thankfully, there are some great gadgets out there that can make it a breeze!

Heat Lamp

This is the cheapest and most traditional option, however it is the hardest to get right, burns a lot of electricity and is definitely a fire risk. If you are using a heat lamp over a plastic storage tub, it’s very easy to overheat your chicks and requires close monitoring. 

To adjust the temperature as the chicks get older, simply raise the bulb further away from the brooder. A general rule is to start with the lamp 18” above the chicks and raise it by 3” every week. However, always watch your chicks behavior and use that as a guide.

Heat lamps are definitely a fire risk! Be very careful about how you are securing them and that there is nothing flammable near by. Of course, all of your chicken bedding is entirely flammable, so triple check how it is secured. 

Heat lamps are also prone to burning out, so it’s best to have 2 heat lamps set up if you have the space. Lastly. The red heat bulbs are recommended over the white heat bulbs because white light 24-hours a day stresses the chicks and can lead to them to pick on each other.

Brooding Heat Plate

Using a brooding heat plate is my very favorite option. It’s a little more expensive than your traditional heat lamp set up, but it’s safer, easier to manage, and results in happier chicks.

The brooding heat plate mimics an environment similar to a mama hen in nature. The chicks quickly learn to go in and out from under the heat plate as they need vs being forced to endure whatever temperature the heat lamp is set up to. The brooding heat plate has adjustable legs so you can raise the height as the chicks grow.

I’ve found the chicks to be much healthier and happier using this method, too. They find comfort being able to hide and sleep in the dark like they would with mama hen, rather than having a light beam down on them 24-hours a day.

Lastly, this method is much safer in terms of fire-risk and uses much less electricity in the long run compared to the traditional heat lamps. I think it definitely pays off going this route!

The Homesteading RD's Product Picks

This 12" x 12" model enables 1-25 chicks to snuggle under a warm surface without burning themselves. Easily adjustable legs to allow it to ‘grow’ alongside your chicks.  It uses a low power 20W consumption which is a whopping 92% lower than a typical 250W heat lamp!

 This heating plate cover is optional, but keeps your brooder plate clean! As your chicks get older, they'll love jumping on top (and pooping on) your heating plate. Easily removable for washing.

Light in the Brooder

Proper use of light is essential to proper chick development, especially if you are using a brooding heat plate (provides no light) instead of a heat lamp. Chicks have circadian rhythms just like humans; thus, they function best with light during the day and dark at night (another reason why I’m not a fan of heat lamps). 

As with most things, mimicking what happens in nature is the best strategy. Having your brooder next to a window (but out of direct sunlight) will allow the sun to do the work for you.

If your brooder is in a garage or basement with limited light, make sure you have a light on during the day. This will allow the chicks to get busy doing their thing and of course see where their food and water is. Putting a light on a timer can make this a breeze!

Water Options in the Brooder

Having clean water available at all times is essential for chick health. Signs that your chicks aren’t finding water are bluish beaks and sluggish behavior. Deaths typically occur after 4 days of no water.

Water Introduction

To make sure that your chicks know where the water is, dip each of their beaks into the water as you add them to the brooder. They may not drink on their own right away, but after a few chicks figure it out, the rest will follow. Start with the waterer fairly close to the heat source, then gradually move it away as the chicks get older.

Water Additives

There are several additives you can buy to mix into water such as chick electrolytes and chick probiotics, however, I’ve always had good luck with plain ol’ water. Now, if you are ordering hatchery chicks who have been mailed over a long distance, you may want to add one of those products. Another option is to perk them up with a little sugar water (½ cup per quart of water).


Newly hatched chicks will need chick-size waterers to start and then graduate to larger ones as they grow, so be prepared to have several sizes on hand. See my recommendations below!

The Homesteading RD's Product Picks

I love a good combo deal! This set will feed up to 15 chicks until they are 3 weeks old. A great starter set with a shallow waterer base to keep the chicks from drowning. 

This is the perfect size for when chicks are 3+ weeks old and need an upgrade. I like this model because it has a handle for easy moving and stringing up if you want to hang it to keep the mess down.

While 5 gallons feels like a lot, this is a great size for when your chickens are big enough to move out to the coop. A larger waterer means you have to fill it less often, which is great when you leave for a weekend get away!

Food Options in the Brooder

Now that we have water covered, it’s time to talk about food! While chicks can survive for 2 days off of the nutrients they absorb from the yolk, it’s best to offer them food right away (after they’ve had their first drink of water).

Starter Feed

When your baby chicks are days old, it’s best to start with a commercially formulated starter feed (this is the one that I use). This will provide all the nutrients that your chicks need, including a higher protein content to support their rapid growth in the beginning. Chick starter is typically in a “crumble” form, so grit isn’t necessary yet.

Grower Feed

When your chicks are roughly 5 weeks old, then it’s time to move to a commercially formulated grower feed (this is the one that I use). Grower feed has a slightly lower protein content since the chicks growth won’t be quite as fast. Less protein typically means less expensive, too! If your grower feed formulation includes whole grains, make sure to offer chick grit at this point so that they can properly digest their food.

Medicated Feed

You may find at your feed store that some starter feed says that it is medicated. This is to prevent the chicks from getting coccidiosis, which is an intestinal disease caused by parasites. I’ve personally never used medicated feed and have never had an issue. 

Tip #1: Not sure how much chick feed to buy? Each chick will consume roughly 10 lbs of feed during the first 10 weeks of life.

Tip #2: Do not switch your chicks to layer feed until they are ready to lay (18-20 weeks old). The calcium content in layer feed is much too high for chicks and can damage their kidneys.

The Homesteading RD's Product Picks

Complete nutrition for young and growing birds from 0-8 weeks old, without pesticides, medications, or genetically-modified ingredients.  Getting a 40-50lb bag at your local feed store is more economical, but this can get you started in a pinch!

I love a good combo deal! This set will feed up to 15 chicks until they are 3 weeks old. A great starter set with a shallow waterer base to keep the chicks from drowning. 

This is the perfect size for when chicks are 3+ weeks old and need an upgrade. I like this model because it has legs to keep the feed elevated from messy bedding, plus it has a loop on top to allow it to be hung, if desired.

After going through MANY different feeder designs over the years, this is the absolute best for teenage or adult chicksn. It holds a lot of feed (making vacations a breeze), plus it eliminates waste from spilled feed. It'll pay for itself in the long run!


I briefly mentioned grit above, but let’s talk about it in more detail here. Chickens don’t have teeth to chew their food, so they need to eat small rocks (or grit) to do the chewing for them! Grit is stored in a highly muscular organ called the gizzard. The food is then ground up here into a smooth paste, allowing for proper digestion.

When chicks are given “crumbled feed” (what’s in the product table above), this easily turns into mush so grit isn’t necessary. However, chicks do go crazy for it and it can aid in overall digestion so providing it early certainly won’t hurt! 

Once you transition your chicks to a whole grain feed, fresh greens or any other food beyond crumbled feed, they absolutely need to have grit available! I put it in a small dish by the feeder. Grit comes in 3 different sizes: chick grit (#1), poultry grit (#2) and large fowl grit (#3).

Brooding in Poultry – Extra Tips

Happy chick behavior signs

Raising baby chicks is easy once you know how to read their behavior. They should fluctuate between sleeping soundly and being energetic and curious. They should be freely eating and drinking without picking on each other.  A clear sign of a chick who is unwell is one who has poor growth, weakness, diarrhea, stands with a droopy head and wings with its eyes closed.

If you find that your chicks are picking on each other, provide more brooder space, feed/water space, and reduce the amount of light. Make sure that you are using high-protein starter feed and consider reducing the brooder temperature by 5 degrees as well.

The chicks should be spread evenly throughout the brooder (see temperature section above for more details), and communicating with soft peeping noises. Shrill, loud calls is a concerning sign – either they are too cold, stuck, or had something placed on their foot (a waterer that was set down). Sleeping is common, however, they shouldn’t be sleeping an excessive amount and wake easily.

Check for pasty butt

This is the biggest thing to be on the look out for during the first 2 weeks of life. Pasty butt is where the chick’s droppings “paste” over their vent, causing a blockage. If left untreated, the chicks become toxic resulting in death. Pasty butt is more common if the chicks are chilled, overheated or eat more than they drink.

Every morning, take a look at each of your chick’s vents to see if they need an intervention. Run lukewarm water over their bottom until the hardened stool softens up and falls off. Do not attempt to pull it off prematurely as this can pull off feathers and potentially tear their delicate skin. Once the area is clean, gently blot the area with a towel and apply a little vaseline. The vaseline protects the delicate area and keeps future stool from sticking.

When returning chicks back to the brooder, make sure that other chicks don’t peck at the area. Chicks are curious creature and are drawn to peck at anything that is red in color. They seem to go for freshly washed bottoms. This is another reason why I love to use the chick heating plate rather than a heat lamp; they can hide under there where it’s dark and dry off quickly.

Roosting bars

Once your chicks reach 3-4 weeks of age, provide them with low perches to roost on. This will provide good entertainment during the day, plus they’ll naturally want to start roosting at night as well. Plan for 4 inches of roosting space per chick.

You can make your own chick roosting bars out of scrap wood laying around, otherwise there are some pre-made options out there, too!


The majority of your chicks’ intake should be their well-balanced feed, but a few treats given sparingly can be fun! The chicks enjoy the variety and treats can be a great boredom-buster. Some great chicks treats would be crushed meal worms, alfalfa sprouts or scrambled eggs. Never throw large weeds or blades of grass in the brooder as they can develop crop impaction.

FAQ About Brooding in Poultry

How long is the brooding period?

The brooding period typically lasts until the chicks are fully feathered, which is around 6 weeks old. Having feathers instead of down will help the chicks trap warm air against their bodies and no longer need a heat source. At this point, as long as the ambient temperature remains above 65 degrees, the heat source can be removed.

If you move them outside to their coop and the temps dip below 65 degrees at night, I’d still provide a heat source in the coop for a few weeks when they are sleeping. Observe them and notice their behavior. If they are huddled together and cheeping noisily, they’re too cold. If you don’t have electricity wired into your coop, an extension cord or two strung from your house will work.

Can I bring my chicks outside on a warm day?

Once they are 2 weeks old and it’s a warm (70+ degrees), sunny day then absolutely! They will love the opportunity to enjoy some sunshine and scratch around for treats. Just keep an eye on them and make sure they aren’t chirping loudly or piling on top of each other. If this happens, bring them in right away to their heat source.

Another thing to make sure is that they are in a confined, safe place. Baby chicks draw in all sorts of curious creatures from cats and dogs to foxes and hawks. You could bring out your brooder pen if it’s mobile, otherwise check out the portable chicken run option below!

The mesh walls allow for a 360-degree view for your chicks, while the open bottom design allows them to enjoy the grass for comfort and foraging and to keep you from having to wipe out messes! 

How do I keep the waterer clean?

This may seem simple, but once you have some rambunctious chicks in your care, you’ll realize what a feat this really is! With the waterer sitting directly on the bedding, chicks will often poop in there and kick in a bunch of bedding while they are scratching about.

My best tricks to avoid this is to raise the waterer a couple of inches above the bedding, but not too far that the chicks can’t reach this. I don’t recommend doing this until the chicks are at least a week or two old, though.

The best way to do this is to hang the waterer on some rope. If your waterer doesn’t have a hook on it, you can purchase a Hanging Harness. Suspending the waterer not only keeps it clean, but it keeps it from being knocked over as well. If hanging isn’t an option, then put down a block of wood or a few ceramic tiles and place the waterer on top of those.

How do I introduce chicks to my flock?

If you already have an adult flock, the idea of integrating your new chicks can be nerve-wracking. Thankfully, with a little planning, you can introduce them smoothly with very little ruffling of feathers. I’ve been introducing chicks to my flock for years and have never had any issues.

The best way to introduce your chicks to your adult chickens is to wait until the right age and to do it slowly. You never want to just throw them all in together and hope for the best.

The best age to introduce them is when the chicks are teenagers (~2 months old). That way they are old enough to be able to hold their own if they have to, but they are not so large that they pose a threat to the existing pecking order.

Next, find a way to have them exposed to each other for a few weeks before letting them interact directly. For me, my coop and run are divided in half so it’s easy to keep the adults on one side and the chicks on the other. Placing a dog kennel (see photo below) or chicken tractor near your coop would work, too. Same with building out a corner of your run into a brooding cage!

Teenaged chickens in a dog kennel outside for protection

This method works well because it allows the adult chickens and chicks to get accustomed to each other while keeping the chicks safely protected behind the fencing. It also helps to keep the chicks confined to their new coop area so that they establish the new location as their home before letting them free range. You know they are are ready to mingle together when they’ve lost interest in each other and go on about their business.
