Duck picking on hen

[Jenlamb35]

I have a 1 year old mallard that has started picking on one particular hen. I think because she cowers and lets him when the other hens won't. He has really bruised her comb. What can I do to stop this other than find a new home for him? I don't know if he's trying to breed her but he doesn't do it to any of the other hens. I have one female duck.

Separate the ducks from the chickens. If he is not trying to breed her yet (and I think he very likely is) he will soon start. Drakes have penises - roosters do not. The reproductive tract of a chicken is not meant for the insertion of 'objects'. He can seriously injure or kill her.

It is time to separate the Ducks from the chickens...His hormones are kicking in to high gear and he will injure the hen.

Wow I had no idea it could get that serious. I just thought they could be in the same pan. I will get them separated immediately. Thank you.
