Does anyone have advice as to how to tame an aggressive Ancona drake? He is not aggressive with our female ( we currently only have 2 ducks). He is aggressive with me and our family members - nipping, biting and circling around us. He hisses and and when trying to feed him, he lashes out and tries to bite. He is about 7 months old and has been doin this for about a month. Would more female ducks help? I would feel terrible giving him away but nothing seems to help and my kids are afraid of him now.
