I just got 6 baby orphingtkn chickens. I believe I got them when they were about two weeks old. They are going on 3.5-4 weeks now and I’m not sure what to do with them with the winter weather. We live in a cold climate so right now in February it’s 30-40 degrees in the day time and about 20 degrees at night. They are very lively pecking around and even flying some of them. And I feel like they may be ready to get out of the brooder box. I have been doing me best to wean them off the heat although not even totally sure I’m doing that right. When should I introduce them to the outdoors?
