Stage 1 — weeks 0 to 6
Two conditions have to be true at once, and the calendar is only a proxy for either of them.

The short answer
Chicks can move outside when two things are true: they are fully feathered, usually around five to six weeks, and the coop’s overnight temperature is close to what the brooder had already come down to. Following the published schedule, the brooder is at 75 F in week five and 70 F in week six, so a coop that stays near that is a safe destination.
Feathering. Down does not insulate a wet or cold bird; feathers do. A chick is ready when the down is gone and it is wearing proper feathers, including across the back and around the neck. Breeds differ by a week or more, and within a hatch individuals differ. Look at the birds, not the calendar.
Temperature match. This is the one people skip. Penn State’s schedule has the brooder at 75 F in week five and 70 F in week six. If your coop drops to 40 F overnight, moving a week-five chick from a 75 F brooder into it is a 35-degree step in one evening. That is a setback at best. Either wait until the brooder has come further down and the birds are further feathered, or make the transition gradual.
The approach that works is to shrink the gap from both ends rather than making one jump.
This is the practical reason the coop should be ordered around week three. A flat-pack coop can take a weekend to build, deliveries slip, and a batch of feathered six-week-olds climbing the brooder walls is not the moment to discover you are missing a panel.
Ready means the coop is assembled, the run is enclosed with half-inch hardware cloth rather than chicken wire, bedding is down, and the feeder and waterer are in place and full. Young birds moved into an unfinished setup are the birds most likely to be lost to a predator, because “we will finish the run tomorrow” is a night with a gap in it.
| What you see | What it means |
|---|---|
| Piled in a corner of the coop at night rather than roosting | Normal for the first nights; they learn roosting |
| Refusing to go in at dusk | They have not learned the coop is home. Confine for another few days |
| Huddled and inactive during the day | Too cold. Consider moving them back or adding shelter |
| Panting, wings held out, in shade | Too hot. Young birds handle heat worse than cold |
| Not eating or drinking on day one | Show them where both are. A new space disorients them |

A coop, the mesh that makes the run safe, and bedding for the floor.
Omlet
7.8 sq ft interior
A plastic coop that hoses out, with published interior dimensions you can actually check — and once you check them, a six-hen claim that only works because the run is permanently attached.

Galvanized hardware cloth
1/2 in mesh, 19 ga
Half-inch welded mesh in 19 gauge steel — not chicken wire, which keeps chickens in and keeps nothing out, and is the single most expensive mistake a first-time keeper makes.

Triple-screened, 99% dust-free
Ordinary pine shavings with an unusual claim attached: triple-screened to 99 percent dust-free, which is the one bedding spec that matters in an enclosed brooder.

Usually five to six weeks, once they are fully feathered and the coop's overnight temperature is close to what the brooder had come down to. Penn State Extension's schedule puts the brooder at 75 F in week five and 70 F in week six, so a coop staying near that is a safe destination. Feathering varies by breed, so judge the birds rather than the calendar.
For supervised daytime outings in mild weather, yes, and it is a good idea — it builds cold tolerance and familiarity with the space. Living outside full time at four weeks is usually too early, because most chicks are not fully feathered and the overnight temperature drop is a large step from a 80 F brooder.
Move them after dark, when chickens are docile and will wake up where they went to sleep, then confine them to the coop and run for two or three days. That is what teaches them the coop is home. Skipping the confinement period usually means a week of catching birds at dusk.
No, and it is a poor idea: a lamp in a wooden coop full of dry bedding is a fire risk, and birds that come to depend on heat are in real danger during a power cut. If the coop is genuinely too cold for them, that means they are not ready to move yet rather than that the coop needs heating.
