I had two male white crested a, Doug and Stan. In May they were one year old. Both were very loving and friendly. In late May, Doug was abducted and murdered by a fox we presume. Since then Stan has been very mean towards me, chasing after me and biting at my feet and hands. I have tried everything, picking him up and carrying him around, grabbing his bill and holding it until he relaxes, telling him no, pushing him away, even putting my body on him to show him I am in charge. Nothing works, he is very aggressive. We thought maybe he was lonely, so we added 3 new drakes in June. It took a few weeks before we put them together, but now they are together in the same yard all day and the same coop at night. Stan is still very aggressive and won't let me near the babies. He recently has begun pecking at the smallest of the babies, Pedro. We have had to treat Pedro's head a couple times because of wounds. I hate the thought of finding a new home for Stan, but I don't know what else to do....I can't even go out into my own yard without being attacked. And I have to continue to reprimand him for several minutes, then even if I walk to another part of the yard, he comes at me again. What do I do?
