I'm still having issues with my ducks. I've got 1 drake just over a year old who up until this year lived with 2 females absolutely fine. Very fertile and I hatched out a really nice set of ducklings from them.
Unfortunately the fox had one of my original 2 females which left the drake with 1 female. When the females from the hatch were big enough I put them out with the drake and older duck approx. a month ago. He was very umm keen shall we say and quickly pulled the feathers from their necks and made their necks pink. I separated him for 2 weeks and have tried again but he's done the same thing. The minute the young ducks try to go over to one of the 3 water drinkers he is in there like a shot and they run off. The older duck is fine and stays with the drake.
At a bit of a loss what to do... I don't really want to get rid of him as he's such a nice drake and he didn't do this when I introduced him to the 2 ducks last year, but for some reason he's too keen and now when he advances the 3 young ducks run off. I would have thought after a month they would have settled down?
