My dad called this am to tell me that 2 of our 3 runner ducks were found dead when he went to feed them. Something had tried to pull them through the fence and had eaten their necks. the third one was still alive with blood on his neck,back and wing. We brought him home with us and got him cleaned up. He has very small teeth marks in his bill and bite wounds on his neck and wing. His name has been changed to lucky duck. We set traps for what ever it was looks like a weasel or possibly a mink was to blame.
