I didn't know you could keep males together without them fighting especially if there are girls around. My husband seems to think they will eventually get mean if they are separated from the girls. Is there truth to that? I know some birds (parrots) do get mean if they are never allowed to mate, is this true of chickens? Would it be wise to separate out all of the males and rotate their time with the girls? I am not interested in breeding. We enjoy them as pets and eventually for the eggs to eat. The boys all get along well so far but they don't have spurs yet. They are only about 10-12 weeks old.
