I've recently integrated my silkies into the coop with 2 older chickens. The older ones seems to be behaving themselves. They got testy for a day or 2 but they never pecked the babies or kept them from food. But unfortunately, the silkie babies won't leave the coop. Sometimes 1 or 2 of them wander out but they stay right in the coop for the most part. I understand why they wouldn't on a chilly day but yesterday was about 80* and only one came out to wander around. Any ideas why or what I should do? Should I shoo them out on a nice day or let them figure it out on their own?
