I just released my 6 chicks into the run with the other 6 that I already had. You get ones are about 9 weeks older ones are about 16 weeks. The younger ones have been in a separate cage for about 2 and a half weeks inside of the coop so the older ones would start to get used to them. The older ones are pecking at them a little more than I thought they would. My question is how long should I expect the older ones to peck at the younger ones before they all "get along"??
