Newer to ducks, have never had a male. So we found a pair of call ducks close to home. They seemed perfectly nice in quarantine but ever since we let them loose with the flock, the drake will not leave our other three domestic ducks alone (a Pekin, Swedish, and a runner). He's pulling feathers trying to mate them, which they don't want, and they are now afraid to go into the coop and stay as far away from him as possible. I think the Swedish may have hurt a leg trying to get away from him. He mates the other call duck regularly and she seems willing. I do have two other runner hens that are growing up. Will six females be enough for him so he can stop being so violent, is this how ducks are, or should we get rid of this one and look for another? Thanks for the help!
