I have three pens with a 6ft talk fence. One one has turkey's, one has ducks and geese then the 3rd has chickens. A few weeks ago something got all 7 turkey's in one night. A week later it started getting the ducks. There is no sign of going under the fence or anything left. So it has to be going over the top. I did go around in the pasture and noticed some feathers up in a fork of a tree with blood. So looks like it climbs trees to eat it sometime, but once again it's all gone. Any ideas what may be getting them? Heard it could be a bobcat or mountain lion. Ideas or solutions?
