In the last few weeks we have had at least 11 ducks come up missing without a trace. The chickens have not been touched. The ducks include 1 peking, 1 mallard, 3 Indian runner and the rest were mixes between mallards/runners/east indies. They are fenced in on 1/3 Acre. No holes under fence. No extra feathers anywhere. Usually when we have problems there are feathers everywhere, dead bodies and usually chickens. There are also 2 goats in with them. And a goose. I don't know what time of day they come up missing.I know there are red tail hawks here, the neighbor lost his chickens to foxes. I do live in the country. I was just wondering if anyone had any pointers on how to keep birds of prey away if that is what it is. It is just weird that it takes ducks only. The chickens are so much easier to catch!
