This week I introduced my 3 month old chicks to my rooster and four hens. Typically, my older chickens get along well, so I didn't anticipate any problems. I put the new chicks in a crate, and placed them near the run to get acquainted. Then, I waited until dark, and put the new chicks in the coop after dark. That was a week ago, and everyone is alive. However, my rooster has the new chicks on lockdown. They aren't allowed into the run. I feel badly because they're spending hot days in the coop. Is there anything I can try to help them?
