I have 12 hens, 2 pullets, 1 rooster, and 1 cockerel. Can the rooster and cockerel be kept together? Right now the cockerel is in a much smaller coop and run with the 2 pullets. If I move them in with the rest of the chickens will they fight after the cockerel gets older? If so then what else can I do? I know he shouldn't be kept with just 2 hens, but the run they're in now is too small for more than 3 chickens.
