I have had several killed over the past two months...some were locked in the coop missing their heads and then some were just gone with a pile of feathers in the yard...it would get them before I locked them in at night...I swear it was watching my house!!!! We set a trap and the same night we set it we caught a raccoon.....of course we killed him...now fast forward a month or so and I have another one dead in the locked coop without a head, came home the other night and had a big raccoon in the yard again.....I do think your is a weasel b/c of the small hole, mine is definitely a raccoon......it makes me so MAD for something to get mine!!!!!!!!
