I have 4 different age groups of chickens and need to figure out how to get them to all share the same coop. I have 3 Cochins that are 12 weeks (2 roos I believe - anyone interested in buying a golden laced Cochin bantam?) plus I have 3 that are 8 week old mixed standards (2 roos there also) and 8 that are also mixed standards (3 weeks old - not sure but at least 3 roos). The parents of the mixed chicks are a BR rooster and a SW hen and I would like to mix the SW hens (2 of them) in with all. My BR rooster will be culled soon as he is way bigger than the rest and stresses my 2 SW hens out. Well you know the scenario - oldest hens pick on the 12 week old birds; the 12 week old birds pick on the 8 week old birds and of course all of them think the 3 week olds are something to munch on...........all help is welcome at this point!
