Chicks

Chick Care Week by Week: A Brooder Checklist for the First 8 Weeks

Field guide · Updated October 13, 2026 · about 6 min read

Chicks cannot regulate their own body temperature for their first few weeks (University of New Hampshire Extension), so the brooder does it for them. This checklist lines up what extension services say chicks need at each age — heat, space, feed and water — from setup until the heat comes off at about 8 weeks.

Before the chicks arrive

Day one

  1. Get chicks into the warm brooder as soon as possible. Chicks can live on their yolk for about 72 hours, but Penn State says ideally they reach feed and water within 24 hours of hatching.
  2. Dip each chick's beak in the water so it learns where the drinker is (Penn State, UNH, UF/IFAS).
  3. Scatter the first starter feed on paper, an egg-carton lid or a shallow dish; move to a feeder once chicks are eating (UF/IFAS, UNH, Penn State).
  4. Put feeders near the heat but not directly under it (Penn State), and arrange feeders and waterers like spokes of a wheel so every chick can eat and drink at once (UNH).
  5. Watch for about an hour to confirm chicks are drinking and eating, and adjust the heat to their behavior (UF/IFAS). Penn State says crops should be full by the second day.

Week-by-week brooder table

Temperature and space columns as published by Penn State Extension ("Brooding of Domestic Fowl"), which says to start at 95°F at chick level, directly under the heat source, and lower it 5°F per week until the normal daily temperature of 62–65°F is reached. UNH gives 90–95°F in week one, measured 2.5 inches above the litter; Missouri starts at 95°F in cold weather and 90°F otherwise. UF/IFAS and Missouri give ½ square foot per chick early on, and Missouri 1 square foot from 4 to 8 weeks.

Behavior signs from Penn State, UNH, UF/IFAS and Missouri Extension. Missouri sets heat lamps about 18 inches above the chicks in week one and raises them about 3 inches a week, adjusting by chick behavior, not air temperature alone.

Feed and water

Health basics

Penn State says egg-type chickens should be vaccinated for Marek's disease at the hatchery, so ask when you order. It also advises a diagnostic-lab diagnosis for any deaths before giving medicine. For sick chicks, contact a veterinarian or your county extension office.

The CDC notes that outbreaks of Salmonella linked to backyard poultry are common, and that poultry can appear healthy and clean but still spread germs that make people sick. Its backyard poultry guidance:

When the heat comes off

UNH says the brooder can be removed once the temperature under it reaches 65–70°F or matches the outside temperature. Missouri says to keep providing heat until chicks are well feathered, because removing it too early makes respiratory problems more likely; in winter, heat may continue for six weeks just to keep waterers from freezing. Penn State's schedule reaches room temperature at 8 weeks. Plan the move to the coop with adult space in mind — the coop space calculator works it out per bird.
