Right now I have 3 drakes and 4 female pekins. Everyone was living together and mating together just fine up until about a month ago. I know they're mating behavior is aggressive but I was never too worried about it until one night in there pen, where there is no pool, a female was completely attacked. There was both feathers and skin ripped from the back of her neck. I nursed her and she's doing fine now but I'm scared the same is going to happen to my other females. We were planning on killing who we thought was the most aggressive drake, and hopefully will this weekend. But it's not just him. Also, the only female who's neck isn't missing feathers, will participate in attacking the other females. Now I have two ducks who are 'sad'. A female and a pale beaked male who has always been picked on for looking different. They just walk around away from everyone else with there heads down. Last night I had to put the female in our shed because none of the other ducks, including the females, would let her drink water. So my question is, will killing the most aggressive male stop this? There will still be two males but the pale beaked one is submissive. And will this also stop the females from being aggressive too? I don't want to have to kill one of my egg laying females if I don't have to. Any help would be appreciated, thanks!
