I have 5 pullets that were about 8 weeks old when I introduced 3 chicks that were 4 weeks old. They have all been together for about 2 weeks now but they are still segregated into two groups. The big chicks will still peck the little ones if the little ones try to eat while they are eating. But at night they all share a roost. Five on one side and 3 cuddled up on the other end. Will they ever integrate?
