Hi we are having some problems with our cockerel. First of all we were only supposed to get pullets but he slipped through. He attack one of the girls last night and this morning he was very aggressive with the girls. Not letting them leave the coop and pecking and jumping at them. We are not sure what to do. Placed ads for someone to take him for free but until we can get ride of him I don't know what to do with him. At the moment we have him in a dog crate separated from everyone. Any advice would be great. Thanks!
