When Can Chicks Go Outside?
Ultimately, this will be determined by the chicks age, your location, outdoor temperature.
When chicks are hatched by momma hen, they can be outside in colder temperatures. If the weather is too cold for the babies, they will huddle under mom using her as a heater.
As long as the temperature outside is at least as warm as the brooder, chicks can go outside to play during the day.
Chicks can be moved into the outside henhouse permanently when the outside low temperature matches the target brooder temperature.
Chicks can also move outside when fully feathered, around 6-10 weeks old
