Our chicks and ducklings were purchased together. I kept them together for a very long time until the ducks got too big to be in the same area. The ducks are Pekin and seem to both be drakes. (unfortunately). Now all are about 4 months old. The chickens have a yard and the ducks are free range. We have a 1/4 acre pond but they will not stay out there. They used to go out for a while in the morning and then come back up to the chicken yard and stand outside the gate & act like they wanted in. So I did... big mistake. They attacked the chickens. Trying to pin them and grabbing them by the neck! Since I've kept them separate. But I haven't been able to let the chickens free range... So...yesterday I noticed that the ducks (who refuse to go to the pond now at all. I keep water & food for them by the barn & chicken yard.) anyway, they are sticking their heads through the fence and grabbing the chickens by the necks!!! What is wrong with these ducks?! I know they're not happy, but I don't know what to do. I think it's time to re-home them. Anyone have any suggestions!!???
