One other thing. I think sometimes you have to wait the cocky (pardon the pun) cockerels out. My turken cockerel, Impy, came this_________close to the chopping block many times. If he wasn't aggravating the pullets with his testosterone overload, he was bothering some other living being.
Now that some of the pullets are laying he's turned into a fine gentleman. Very watchful for danger. He even refuses to go into the coop at night until every single pullet is safely inside.
I have, at last count, 30 pullets and hens. Much too many for one roo to keep track of.
