I have two Muscovy drakes and three other ducks. One drake was the leader of the pack for a year and now the tables have turned and the #2 drake has taken over. He has become so aggressive that he will not let the other drake anywhere near the other ducks and keeps his apart from the group all day. They are fighting. This morning I let them out of the house and the new #2 had blood all over his wing. He is becoming a bit skittish around us also and seems rather sad. It almost like the top drake is trying to get the other male to leave the yard and never come back. We are new to this so, any advice on how to handle the overly aggressive male and get him to accept the other one back into the group?
