Hi y'all. I have 6 chicks that are 7 weeks old. I moved the out of my brooder box with heat to a brooder box coop (separated but adjoining my main coop) with no heat. The chicks go in and out fine during the day. But every evening they pile up in the corner by the door. I have been going out each evening and moving them into the brooder and locking them in til morning. Will they eventually get the idea and go on their own at night? Am I making it worse because they know I'm coming? They've been out there a week. How long should I keep them from the fully grown hens?
