I may have a serious roo problem. I have a flock of 15 buff orpingtons, 2 roos, 13 hens and an extra mayer meal maker that turned out to be a roo leghorn. The leghorn is not staying long even though he is a nice guy. They are about 17 weeks old. The largest buff roo has been aggressive to the hens. All of the hens try to stay out of his way, but he will just grab a hen by the wing or pull a feather out. The poor girl will just wail. He is not aggressive with me at all and will nicely eat out of my hand. I am not sure how to handle this issue. Please help.
