I have lost 4 ducks and 2 chickens in this manner. I know we have a weasel out back that we are trying to trap. One duck was carried off, you could see the tracks in the snow. one chicken had its head decapitated, no blood, body left untouched. One chicken was killed just like this pic of the duck... and 3 other ducks just like this also. I am in the process of making weasel boxes to try to trap them that way besides reg. traps set out. What else could kill my ducks in this manner? Nothing else on the body was touched, just the neck , stripped completely. Anyone have a clue? Or how better to trap this sort of preditor. My ducks and chickens are fenced in with a coop.
