Quick background: I have a mallard hen that I found as a duckling by itself this spring, and raised. I then have 2 drakes that I was told are White Layers from metzer farm and a muscovy hen that are all 19 weeks old that I bought to be the mallards friends, straight run from a local farmer. Now to the issue: The white layers which are now grown to two full size drakes are getting very aggressive including sexually. The muscovy has no problem getting away, not to say they aren’t becoming an issue for her. But the mallard is in poor shape and I’ve had to separate her for now. Overnight she is no longer flying and seems frail and she now hides from the white layers, and when I got her out of the run the white ducks charged and mounted her until I got them off. Neither the mallard or muscovy have started laying yet and to them this probably just seems violent. I do not know how to handle this, but I do not want to put them all in the coop together again, unless they can get along, and I don’t think I could comfortably get them through the New England winter seperated. I do not want more ducks, at least until next spring, and I do not want to slaughter one or both of the drakes though it seems like the only option and I hope people here have better ideas. Thanks for your time and help!
