OK- the easter bunny brought us four chicks: 2 RIRs and 2 Auracanas that lay brown eggs so we think ther are really Aumericanas. We loved them so much we got 2 barred rocks a couple of months latter. The BRs are almost as big as the other four now so I decided to integrate them. It didn't go so well. I went to check on them and they were hidding behind the hen house in our coop. The other girls peck and chase them. What should I do?
