Your first 8 weeks of backyard chickens
Getting chicks is easy. Keeping them alive and thriving through the first two months is where the learning happens. Here's what to expect, what to watch for, and when to stop worrying.

Eight weeks. That’s how long it takes a fluffy, peeping ball of down to become a feathered, opinionated teenager ready to move outside. The brooder phase is where most beginner mistakes happen — not because it’s hard, but because nobody tells you what “normal” looks like. This is what the first two months actually look like, week by week.
Before day one: get the brooder ready first
The single most important rule of chick-keeping: your brooder must be set up, warmed, and running before your chicks arrive. Chicks are shipped as day-olds via USPS, often spending 24-36 hours in transit. They arrive cold, stressed, and thirsty. You need to put them somewhere warm immediately.
A brooder is just a heated, contained space. A cardboard box, a plastic storage tote, or a purpose-built brooder — any of them work for the first few weeks. What matters is the heat source and that they can’t escape.
The one thing that saves the most worry: choose an electric brooder plate (like the Brinsea EcoGlow) instead of a heat lamp. Brooder plates are the leading cause of not having a coop fire. Heat lamps work — billions of chickens have been raised under them — but they also cause fires when they fall, tip, or get bedding too close. Electric plates use 18 watts instead of 250, require zero hourly check-ins, and the chicks love them. Start there.
Set up the brooder 24 hours early. Get the temperature under the plate to around 95°F at the surface level. Have fresh water ready, have feed poured, and have a thermometer reading. Then go pick up your chicks.
Weeks 1–2: the heat-and-eat phase
Your chicks arrive and they are very small and very loud. Here’s what to do:
The first 30 minutes matter most. Dip each chick’s beak into the water — gently, just enough that they feel it. This teaches them where the water is and gets them hydrated after transit. Do this for every single chick before you put them all in together.
Read the chick pile, not a thermometer. The best indicator of whether your brooder is the right temperature is how the chicks behave:
- Huddled directly under the heat source, pile-up style → too cold. Lower the plate.
- Scattered to the edges, away from the heat, panting → too hot. Raise it.
- Spread throughout the brooder, eating, drinking, running around → exactly right.
This is why brooder plates are better than lamps: the chicks can self-regulate. They crawl under when cold, emerge when warm. The thermometer is a backup, not the primary tool.
Feed and water are constant. Chicks eat and drink constantly for the first two weeks. Refill water every day, or more in hot weather. Keep feed available at all times — they don’t overeat. Use chick starter crumbles (medicated unless they were vaccinated at the hatchery). No treats for at least the first two weeks — their digestive system is still developing.
Expect mess. A lot of it. Pine shavings go everywhere. Waterers get poop in them by the second day. Change bedding every 2-3 days minimum. A wet, ammonia-smelling brooder causes respiratory problems.
Normal chick behaviors that look alarming but aren’t:
- Sudden sprinting for no reason (“zoomies” — completely normal)
- One chick lying flat, appearing dead, then bouncing up immediately (napping in unusual positions)
- Chicks pecking aggressively at each other (sorting out hierarchy — watch for blood, but mild pecking is fine)
- A lot of chirping (they’re chickens; they chirp)
Weeks 3–4: the feather explosion
Around day 14, you’ll notice pin feathers emerging along the wings. By day 21, your chicks look like miniature punk rockers — some feathers, some fuzz, extremely awkward. This is completely normal.
The temperature requirement drops 5°F each week. By week three, you’re targeting about 80°F under the plate. They’re also significantly more active and will start attempting escape from the brooder. Raise the sides or add a cover with ventilation.
This is also when you’ll notice pecking order establishment, and it will occasionally look violent. Chickens are not gentle with each other. As long as there’s no blood drawn and no single bird being isolated and pile-attacked, let them sort it out. The hierarchy they establish at three weeks will basically hold for life.
Brooder size matters more now. The rule of thumb: half a square foot per chick for the first month, one square foot per chick after. A 4-cubic-foot plastic tote works for four chicks through week three; by week five, you’ll need something larger or they’ll start cannibalizing each other (crowding causes feather-pecking, which causes blood, which escalates fast).
Grit becomes necessary. Once chicks start eating anything other than crumbles — if you give them any treat, any greens, any insects — they need grit (small stones that go into their gizzard and grind food). Chick grit is available at any feed store. Sprinkle it like salt over their feed a few times per week.
Weeks 5–6: the teenager phase
By week five, most breeds look fully feathered except for some patches of remaining fuzz around the head and neck. They have opinions, they have social dynamics, and they are increasingly loud.
Temperature-wise, they’re close to ready for the outdoors. If your outdoor temperatures are above 60°F during the day and above 50°F at night, they can start going outside during daylight hours. Don’t put them outside in the cold overnight yet — they still need the brooder for warmth until they’re fully feathered.
The hardening-off period: like hardening off seedlings, you want to expose chicks to outdoor temperatures gradually. Start with an hour outside in a sheltered spot during the warmest part of the day. Build up over a week until they’re outside all day. Watch them for shivering — if they’re shivering, it’s too cold.
This is also when the coop should be ready, cleaned, and predator-proofed. If you haven’t already, do a night inspection of the coop with a flashlight: look for gaps wider than half an inch anywhere in the run. Raccoons are stronger than you think and patient in a way that’s unsettling. Hardware cloth on every surface, including the floor if predators can dig.
Weeks 7–8: moving day
At 8 weeks, most breeds are fully feathered and ready to move to the coop permanently. Some cold-climate breeds need an extra week or two. The test: if temperatures won’t drop below 50°F overnight and the birds are fully feathered, they’re ready.
Transition tip: move them in the evening. Chickens have terrible night vision and are docile in the dark. They’ll wake up in the coop confused but settled, and by the second morning they’ll understand where home is.
The first night is the hardest for you, not them. You will be tempted to go check on them every 15 minutes. They’re fine. Check once, make sure everyone is inside and the door is latched, then go to bed.
Water freeze management starts now if you’re in a cold climate. Nipple waterers freeze; traditional fonts freeze. A heated water base ($30-50) is worth it — frozen water means no water, which means dead birds within 48 hours in winter. Add this before the first hard freeze, not after.
The things you’ll worry about that turn out fine
Every beginner worries about the same handful of things. Here’s the honest assessment:
“One of my chicks seems weak.” In a hatchery batch, one or two runts are normal. As long as they’re eating, drinking, and not being bullied into a corner, give them a week. If they stop eating or show labored breathing, that’s different — seek advice from BackyardChickens.com forums or a vet.
“They’re not laying yet.” If your birds are under 18 weeks, relax — they can’t. Most breeds start at 18-24 weeks. Don’t rush them.
“My eggs look weird.” First eggs from new layers are almost always weird: double-yolked, soft-shelled, tiny “fart eggs.” This is the system calibrating. It normalizes within a few weeks.
“Something dug under the coop.” If it’s just a shallow scrape, it’s probably squirrels or curious animals. If there’s a deep tunnel under the wire and you’re missing birds, that’s a digger — fox or raccoon. Hardware cloth apron buried 12 inches out from the run perimeter solves this permanently.
