When to Move Chicks Outside: A Transition Timeline
When and how to move baby chicks from the brooder to the outdoor coop: feathering, safe temperatures, hardening off, and getting the coop ready for young birds.
One of the most common questions new chick keepers ask is when their fast-growing fluffballs can finally leave the brooder and move outside. The answer comes down to feathers more than the calendar, plus a sensible look at the weather and a properly prepared coop. Move chicks too soon and they can chill, but keep them inside too long and you end up with cramped, dusty, restless birds. This guide gives you a clear timeline and the steps for a smooth, safe transition.

It Is About Feathers, Not Just Age
The single most important readiness signal is full feathering. Newly hatched chicks rely on supplemental heat because their fluffy down cannot keep them warm. As they grow, that down is replaced by adult feathers, and once a chick is fully feathered it can regulate its own body temperature and no longer needs the brooder's heat. For most standard breeds this happens around six weeks of age, but it varies, so judge by the feathers rather than the date on the calendar.
To check, look the bird over for adult feathers across the whole body, including the head, neck, back, and under the wings, with no significant down still poking through. If you still see plenty of fluff, especially along the back and neck, give them more time before they move out without heat.
Factor In the Weather
Temperature is the other half of the equation. Chickens, even young ones, tolerate cold far better than heat once they are feathered, but the transition still needs sensible timing. As a guideline, fully feathered chicks can move to an unheated coop when nighttime lows stay above roughly 50 to 60 degrees Fahrenheit. If your nights are colder than that, you have two good options: wait until the birds are a couple of weeks older and hardier, or provide a safe supplemental heat source in a draft-free coop for the transition.
Harden Them Off Gradually
Rather than moving chicks from a cozy 70-degree house straight into the coop overnight, ease them into outdoor life. On warm, calm days, set the chicks outside in a secure, shaded, predator-proof pen or in the run, then bring them back to the brooder at night. Over the course of a week or so, lengthen their time outdoors. This hardening-off period lets them adjust to fresh air, sunlight, and the natural swing of outdoor temperatures, so the eventual move to full-time coop living is no shock to their systems.

Get the Coop Ready
Before young birds spend their first night outside, the coop must be safe and comfortable. Predator protection comes first: secure every opening with hardware cloth rather than chicken wire, use predator-proof latches, and make sure the run is fully enclosed, including overhead if hawks are a concern. Young birds are especially vulnerable, so do not skip this. Inside, provide:
- Dry bedding such as pine shavings, kept clean and absorbent.
- Good ventilation up high to clear moisture and ammonia, without creating a draft at bird level.
- Low roosts the youngsters can hop onto as they learn to perch.
- Feed and water available at all times, ideally raised slightly to reduce spillage and contamination.
- Supplemental heat if nights are still cool, removed once the birds are clearly comfortable.
Keep Feeding the Right Diet
Moving outside does not change what young birds eat. Continue offering chick starter or grower feed, never layer feed, until your pullets are close to point of lay at around 18 weeks, when their bodies finally need the extra calcium. Provide constant clean water, and once the birds are nibbling greens, bugs, or treats, supply grit so they can grind their food. Hold off on oyster shell and layer feed until they are nearly laying.
One Last Reminder: Integration Is Separate
Finally, keep in mind that moving chicks outside and introducing them to an existing adult flock are two different milestones. Getting young birds into their own coop is step one. Mixing them with grown hens should wait until they are closer in size, usually around eight weeks or older, and must always be done slowly with a see-but-no-touch setup so the pecking order sorts out without injury. Handle the move outdoors patiently, prepare the coop well, and your young flock will settle into outdoor life happily.
Frequently Asked Questions
At what age can chicks move outside?
Chicks can move to an unheated outdoor coop once they are fully feathered, which is usually around six weeks of age, provided outdoor temperatures are mild. Full feathering matters more than the exact age, because it is the feathers, not age alone, that let chicks regulate their own body temperature. In cold climates or harsh weather, you may need to wait a bit longer or provide supplemental heat at first.
How do I know if my chicks are fully feathered?
Look for adult feathers covering the whole body, including the head, neck, and under the wings, with no remaining fluffy down poking through. Around six weeks most standard breeds have feathered out, though some feather faster or slower. Run your eyes over each bird: if you still see significant down, especially on the back and neck, they are not quite ready to give up supplemental heat.
What temperature is safe for moving chicks outside?
Once chicks are fully feathered, they handle mild conditions well, and adult chickens tolerate cold better than heat. As a guideline, feathered chicks can move out when nighttime lows stay above roughly 50 to 60 degrees Fahrenheit. If nights are colder, either wait until they are older and hardier or provide some supplemental warmth in a draft-free coop for the transition period.
Should I move chicks outside gradually?
Yes. A gradual transition is gentler than an abrupt move. Start by letting chicks spend warm daytime hours outside in a secure, shaded, predator-proof space, bringing them back to the brooder at night. Over a week or so, extend their time outdoors. This hardening-off lets them adjust to temperature swings, fresh air, and a new environment before they spend full nights in the coop.
Can I put young chicks straight in with adult hens?
No, not directly. Moving chicks outside and introducing them to an existing adult flock are two separate steps. Even after chicks are coop-ready, integrating them with grown hens should wait until they are closer in size, usually around eight weeks or more, and must be done slowly with a see-but-no-touch barrier. Adding small chicks straight into an adult flock invites serious bullying or worse.
What does the outdoor coop need before chicks move in?
The coop must be predator-proof, dry, and well ventilated without being drafty, with secure latches and hardware cloth over any openings. Provide clean bedding, a feeder and waterer, and low roosts the youngsters can reach. If nights are cool, a safe supplemental heat source for the first stretch helps. Confirm the run is fully enclosed, since young birds are tempting targets for hawks, raccoons, and other predators.
Do chicks still need their starter feed after moving outside?
Yes. Moving outdoors does not change a young bird's nutritional needs. Keep feeding chick starter or grower feed, not layer feed, until pullets approach point of lay at around 18 weeks. Outdoor birds also need constant access to clean water and, once they are eating greens, bugs, or treats, a supply of grit to grind their food. Hold off on layer feed and oyster shell until they are nearly laying.
