I have a male Pekin which I keep separated from my 2 hens due to his over mating one of the girls ( got down to her skin on the back of her neck). My problem is, now that the two girls are separated they seem to be trying to mate one another and now one of the girls (the other one, is is starting to lose a lot of feathers down the back of her neck! I have 2 females that are 22 days old and not ready to be put in with the older girls. My Khaki Campbell tries to push them over and stomp on them). That's another post for another time though. I need to know if there is anything I can do to keep the two older girls from over mating each other. I do allow conjugal visits from my male Pekin at least once a day but that doesn't seem to be enough for a duck! Lol Any advice would be appreciated.
