I have 4 month old chicks who are outside in their coop. We also have 3, 2 month old Silkies, one is really small. The 'babies' are in a seperate cage, within the run, so the big girls and boys get used to them. My question is will the younger chicks ever be able to be with the rest of our chickens? How big should they be? One of our roosters is big and is always showing the other rooster (small polish) and hens who's boss, he bites them!
