I lost only 1 duck this morning. First I will say, they have a coop, but are not locked up at night (they will be from now on though). Things you should know: First - there is a rather large hole in the top/side of the manure pile. About 7-10" around. Second - killed only one duck. Ate his head down to his chest, and left everything else. The rest of my poor ducks are traumatized and haven't come out of their coop all day. Any idea what I have? I'm planning on setting a have-a-heart trap out to see what I can get, but I'm not sure what to bait it with. Thanks!
