My plan is to divide the coop and run to get the pullets out of the house, which is easy enough to do. Should I wait until they are the same size as my current hens to put them all together? I'm a bit concerned about him mating with them and hurting them due to his size. I wish I could just explain to him their babies and to keep busy with the older ladies, lol. Hopefully it'll be within the next week they're out and in the divided coop/run, they're about 5-6 weeks old. The younger chicks need their larger brooder.
