Grace and Baby, My two Ameraucana/easter eggers are about 3 weeks old. Right now I have them in the garage in dog kennel with the heat lamp. It's still pretty chilly but they're none the worse for the wear. I am thinking about moving them into the coop with the rest of the flock (11-Five month olds) I made them a place to get away if the adults start going after them during the day. There is a nesting box they can call their own in the coop. I am not expecting any trouble in the coop. The adults all roost in the rafters except Claire our white silkie who takes the other nesting box along the bottom. I have a heat lamp I would put out there at least for the first week so they can adjust with freezing. I have heard the earlier you get them in with the others, when they are little, the better. I have seen all kinds of post related to this question and just as differing answers. I am in Oceanside CA What does everyone think???
