Hi everyone, i have 4 pullets, 3 months old, and a roo, with 2 pullets 2 months old- i have had them housed next to each other for a couple weeks and when i let them together there is squabbling, being led by the RIR pullet in the older group, they have zeroed in on one chick - i have tried separating the aggressor which works for the most part, but when i let her back in with them, they go after her again... any suggestions? the roo does try to protect her sometimes, but i guess he is still figuring it out-
