A brooder is the warm enclosure that day-old chicks live in for the first 4-6 weeks of life. It is the difference between healthy chicks growing into productive hens and weak chicks failing to thrive. Commercial brooders are available but easily built from scrap materials and a heat lamp or heat plate.

This guide walks through building a simple brooder, the equipment that matters, and the small mistakes that beginners make.

Spring projectBudget: $40-$100Time-limited use

What a brooder needs

  • Warm zone (initial temperature 32-35C, dropping 2-3C per week).
  • Cooler zone where chicks can move to escape heat.
  • Solid sides high enough to prevent escape (35-40 cm).
  • Bedding (pine shavings, NOT cedar).
  • Food and water at chick level.
  • Predator-proof if not in a secure space.

Simple DIY brooder

  1. Use a large plastic storage bin (60 x 40 x 30 cm) for 4-6 chicks.
  2. Drill ventilation holes near the top.
  3. Add a layer of pine shavings 3-4 cm deep.
  4. Hang a heat lamp or place a heat plate at one end.
  5. Place water and feed at the cool end.
  6. Cover with hardware cloth if pets or curious children are around.

Total cost roughly $40-$60.

Heat lamp vs heat plate

Heat lamp

Cheap ($15-$25), provides clear warm zone. Fire risk if not secured properly. Many coop fires start with heat lamps.

Heat plate (brooder plate)

More expensive ($60-$120), much safer, mimics natural mother-hen heat. Highly recommended for first-time brooders.

Temperature management

  • Week 1: 32-35C in the warm zone.
  • Week 2: 30-32C.
  • Week 3: 27-30C.
  • Week 4: 24-27C.
  • Week 5: 21-24C.
  • Week 6+: room temperature, ready to go outside.

Watch the chicks. If they huddle under the heat source, too cold. If they spread to the edges away from heat, too hot. The right temperature, they spread evenly across the brooder.

Food and water

  • Chick starter feed (20-22% protein).
  • Shallow water container (chicks drown easily; add marbles or stones).
  • Refresh water twice daily.
  • Clean food container of droppings daily.

Bedding

  • Pine shavings (NOT cedar – cedar oils harm chick respiratory systems).
  • Paper towels for the first 1-2 days (helps chicks identify food).
  • Spot-clean droppings.
  • Full change weekly.

Common mistakes

  • Too small a brooder (overcrowding causes pasty butt and pecking).
  • Heat lamp too close (can scorch or kill chicks).
  • Deep water dish (chicks drown).
  • Cedar bedding (respiratory damage).
  • Cold drafts on chicks.

Moving chicks outside

At 5-6 weeks, when fully feathered and the brooder is at near-room temperature, chicks are ready to go outside. The first night they need to be locked in the coop securely. Within a week, they will be ranging happily with the older flock if integrated gradually.

Two authoritative resources we recommend if you want to go deeper on this topic:

Frequently asked questions

Possible but unkind. Chicks are social animals and a single chick will be stressed. Brood at least 3.
Local hatcheries, feed stores in spring, or private breeders. Order in advance; popular breeds sell out.
A 60 x 40 cm bin holds 4-6 chicks for the first 3-4 weeks. After that they need more space.
Droppings stuck to a chick's vent. Clean gently with warm water. Check daily; serious if untreated.
After 6-8 weeks. Always integrate slowly with see-but-not-touch first, then short supervised meetings.
