We have 10 mallards 14 weeks old. There are 3 drakes and 7 hens. One drake has developed a tail curl already and I am curious does this make him the dominant drake. The other two have not developed the curl. The 3 drakes are turning to greenheads quickly now. We have not seen any agression from the drakes to each other yet. We do expect once breeding starts it will happen though.
