I have 4 chickens that are 12 weeks old and I am trying to integrate two 8 week old chicks with them. The two babies are getting two big for the brooder, but the big chickens peck at them when I put them in the run. Does anybody have any tips for integrating them? I have them free ranging in the evening and I am hoping that they will get use to each other in the yard, but the big ones just chase them when they cross paths. Does anybody have any tips for integrating them?
