Had one bird that all was left was bone, feathers and head. Other bird was killed chewed around neck. These are 10 12 week olds. Them a small full grown young muscovey was attacked around her neck and beak has teeth marks in it. The Duck is still alive and has been treated. We have killed a possom in there before and just trapped and got rid of a coon. I have an electric wire on the top of the fence, which I forgot to turn on last night. AUGH. I'm thinking a possom again. Don't weasels claimb and just wipe them all out???
