Ok so I released my 13 chicks that are 7 weeks old into the coop about a week ago. I got rid of my whole mature flock before I got them. But I had a 16 week RIR pullet that I kept. The 16 week old pecks the chicks on top of the head. What should I do? Right now the 16 week old is in a small pin within the coop, but I feel bad that she cannot run around with all the bitties. The bitties are: 2 RIR, 4 BO, 1 cuckoo maran, 1 BR, 2 EE, 2 wellsummers, and Hank my new welsummer cockeral. Let my know what your opinion is.
