Currently, I have 6 ducks: three buff hens, two pekin hens, and one pekin drake. The drake has always been a little rough on the hens when mating, but now I think it's getting out of hand. He's done a deal on one of the pekin hens in particular, causing bleeding and scabbing to the back of her head. He's also picked up a habit of chasing one of the buff hens just about every day, running her off into the coop while the others free-range and, if he gets a hold of her, begins to bite the back of her head for no reason, not even to mate. I don't know what to do! I've really been thinking about getting two more pekin hens this May to balance out his overmating, but my family says that we should just give him away to a good home. I care for him just as much as my other ducks and I purchased them as pets. Is there any advice for what I should do? I've separated him in a big dog cage and let him out under my watch.
