Our broody took her chicks outside in temperatures that I thought would kill them (35-40 degrees) when they were only a few days old, she knew when they needed to warm up and would squat down on the ground for them to crawl under her wings. They are 4 weeks old now and very hardy little chicks
She is exhibiting the desire to rejoin the main flock and is back to laying eggs, so I'll probably let her go back to the main coop when the chicks are 6 weeks old. She's still taking care of them to some extent and they sleep under her at night. The chicks will stay in the grow out pen until they are 12-14 weeks old at least. Their pen is only separated by a fence from the other chickens, so they know each other already, but I want them to be bigger before they have to fend for themselves.
