The perfect brooder setup: a first-week survival guide for day-old chicks
8 minute read · published 2026-03-08
A good brooder will get your first-week loss rate under 1%. A bad brooder kills chicks in 48 hours. The difference isn't expensive equipment - it's the right temperature, dry bedding, accessible water, and a quick daily check. Here's the setup that works.
Brooder size
0.5 sqft per chick first week. 1 sqft by week 3. 2 sqft by week 6. A 110-gallon Rubbermaid stock tank holds 12-20 chicks comfortably for the first 3 weeks.
Going bigger isn't a problem - chicks pile on the heat source for warmth and use the rest. Going smaller is a disaster - pasty butt, pecking, and stress losses.
Heat source: lamp vs. plate
Heat lamp (250W, red)
Pros: cheap ($15-25), reliable, you can see the chicks at night.
Cons: fire risk #1 in coops. Clamp + ZIP TIE + chain. Never rely on the clamp alone. Hangs 18-24" above chicks. Red bulb reduces pecking.
Heat plate (Brinsea EcoGlow, Premier 1)
Pros: imitates a mother hen, no fire risk, lower power draw, healthier sleep cycles for chicks (dark at night).
Cons: $80-150 upfront. Chicks need to learn to go under it.
If you're raising chicks more than once, the heat plate pays for itself in safety and power savings. Browse brooders + heat plates.
Temperature schedule
| Week 1 | 95F directly under heat source |
| Week 2 | 90F |
| Week 3 | 85F |
| Week 4 | 80F |
| Week 5 | 75F (most breeds fully feathered) |
| Week 6+ | 70F or ambient if above 65F |
The chicks tell you if the temperature is right. Piled directly under the heat = too cold. Spread to the edges, panting = too hot. Even distribution, peeping quietly = just right.
Bedding
Best to worst:
- Pine shavings (kiln-dried, large flake). Best. 2-3" deep. Replace wet spots daily.
- Hemp bedding. Newer option, more absorbent than pine. Pricier.
- Paper towels (first 2-3 days only). Use a paper-towel base over shavings so chicks find food. Remove after they learn what feed is.
- Newspaper. Don't. Too slippery, causes spraddle leg.
- Cedar shavings. Don't. Toxic aromatic oils.
- Sand. Don't. Chicks ingest it and get impacted.
Water
- Chick-specific waterer with narrow drinking trough (or marbles in a regular dish first week so they can't drown).
- Dip each chick's beak in water as you transfer it to the brooder. This teaches them the location.
- Refresh daily. Wash the waterer every 2-3 days with hot soapy water.
- Add electrolytes (Sav-A-Chick or DIY: 1 tsp sugar + pinch salt per quart) for the first 3 days, especially after shipping.
Feed
- Chick starter (20-24% protein, medicated for first 8 weeks if not vaccinated for coccidiosis).
- Don't feed layer or game-bird feed to chicks.
- Sprinkle a little on paper towel first day so chicks find it.
- By day 2, transition to a chick feeder. Refill once a day.
- No table scraps in the first 4 weeks. Plain feed only.
The daily 10-minute check
Every morning:
- Count chicks. Note any missing or dead.
- Watch behavior for 30 seconds. Active, eating, drinking = good. Lethargic, isolated = bad.
- Refresh water. Top off feed.
- Spot-clean wet bedding.
- Check vent area on each chick for pasty butt (cleaned with warm water + cornstarch).
Common rookie mistakes
- Too hot. Chicks pant and spread to the edges. Drop temp 5F.
- Drafts. Chicks pile against one wall. Move brooder away from window/door.
- Too small. Bullying, pecking, pasty butt. Upgrade brooder size by week 3 at the latest.
- No grit before treats. If you feed anything besides starter, offer chick grit first or skip the treats.
- Mixing ages. 1-week-olds bully 1-day-olds. Same hatch only.
