I have a rooster that I have raised by hand since the time he popped out of the egg. He just discovered he was a "rooster" about two months ago and has terrorized the hens to the point that they hide under the roost and haven't come out of the coop in over a month and he's tried to peck me a few times! He has also been trying to have "relations" with our duck (who oddly enough doesn't seem to mind). Should I be worried? Will he eventually back off? Do I need to separate them?
