I bought two Peking Drake's from someone about 2 weeks ago. I went today and picked up 1 more Peking Drake from the same lady today. All 3 are 4 months old and they have been together their whole lives (minus the last 2 weeks). I put them together and, at first, they all seemed very excited and happy to see each other again, but then they started grabbing the feathers on each other's necks and mounting each other. It was literally a pile of 3 ducks. No one is picking on anyone specifically; they are sharing the fighting equally. I have never had ducks before, so I don't know what to do. Please help!!!!!!
