How to Set Up a Chicken Brooder | Heat, Space & Safety Essentials

One wrong temperature swing or a missing draft barrier can kill day-old chicks before they finish their first feed. A proper brooder setup is straightforward: get the heat right, the space right, and the bedding right, and your chicks thrive from day one. Here is exactly how to do it, from container choice to the pre-arrival test.

The Container: Space Rules and Draft Control

A plastic tote, stock tank, wooden box, or even a small plastic swimming pool works — as long as the sides are solid and the container is off a cold concrete floor.

If the container walls are less than 18 inches high, install a surround (cardboard, metal, or masonite) to block drafts. Clean used containers with a 10% bleach solution (1 part bleach to 9 parts water) and let them air dry completely; a new container still needs a bird-safe disinfectant to remove chemical residues.

Heat Source: Getting 95°F Right the First Time

A standard 125–250 watt infrared heat bulb works well. Suspend the lamp 18 inches above the bedding on a chain — never rely on a clamp alone, which can fail and start a fire. Adjust the lamp height to fine-tune the temperature. Turn whichever heat source you choose on 24–48 hours before the chicks arrive.

Bedding, Feed, and Water Placement

Spread 2–3 inches of pine shavings across the floor. For the first 2–3 days, cover the shavings with paper towels to protect the chicks’ legs — they cannot grip newspaper (it causes spraddle-leg, a permanent deformity) and cedar shavings are toxic. After a few days, remove the paper towels and let the chicks scratch in the pine shavings.

Place the feeder and waterer at the cool end of the brooder, away from the heat source. Wet feed grows mold, and warm water near a heat lamp drowns chicks. Adjust the lip of each station so it sits at the height of the chicks’ backs. Set one thermometer at chick height under the heat lamp and another at the cool end so you can verify the gradient. Cover the top with hardware cloth weighed at the corners to keep predators out and chicks in.

Your 24-Hour Pre-Arrival Checklist

Do this the day before your chicks arrive, and you will not scramble on delivery day:

1. Place the container off cold concrete, away from drafts, windows, and AC vents.
2. Set up the heat source at one end — brooder plate on lowest legs, or heat lamp chained 18 inches above the bedding.
3. Add 2–3 inches of pine shavings, then paper towels on top for the first few days.
4. Place feeder and waterer at the cool end.
5. Put one thermometer at chick height under the heat and one at the cool end.
6. Adjust lamp height or plate legs until stable.
7. Secure the top with hardware cloth.

A stable 95°F and a clean, draft-free space is all a day-old chick needs to start strong. If you are still choosing equipment, compare our top-tested brooder setups here — the right heat source makes the first week dramatically easier.

FAQs

Can I use a cardboard box as a brooder?

Yes, for the first week or two, as long as the sides are high enough to block drafts and the box sits off a cold floor. Cardboard absorbs moisture quickly and becomes flimsy, so plan to transfer chicks to a sturdier container within 10–14 days.

How do I know if my chicks are too hot or too cold?

Chicks that huddle directly under the heat lamp and peep loudly are too cold. Chicks that spread out as far from the heat as possible, pant, or hold their wings away from their bodies are too hot. Comfortable chicks scatter evenly across the brooder, moving between warm and cool zones freely.

How long do chicks need a heat lamp?

Chicks need supplemental heat until they are fully feathered, which takes 6–8 weeks for most breeds. In warm weather, the heat lamp can be removed earlier if the chicks are well-feathered and the nighttime temperature stays above 65°F.
