I have 3 Cochin/turken cross cockerels and 1 Turkin cockerel along with 2 Turkin pullets. I am trying to find good homes for 3 cockerels. I am going to keep one. They are all 13 weeks old (hatched in my incubator) and presently all 6 in the same coop/run. I have another empty coop/run and am wondering how and when to separate them. Should I move the trio I want to breed now or keep the cockerels together and the pullets together until time to breed? I have only had laying hens the past year and a half and have no experience having roosters.
