Something dug into my coop/ run last night and killed all 11 of my 10wk old chickens!! I need help figuring out what it was. Some lost their heads, some have bloody necks and one has a skinned head. Please help me figure out what kind of predator I am dealing with. Whatever it was dug 4 holes under the barn wall to get into the coop/ run. Where you see the birds all piled up - directly under them is a hole that was big enough to pull one through...(we do have 1 that is completely missing)...but it seems as if whatever it was tried to pull 5 birds through at once. 2 other birds were pulled out of 2 more holes (one was missing a head and one's head was skinned). 1 bird was found next to the 4th hole. There were 4 holes... 2 not more than 1 1/2 inches diameter....1 probably 2 inches diameter and the other 3 inches diameter... Our baby rooster was found away from the holes and sort of by himself. All were in a fully enclosed coop / run. The only holes are in the GROUND on the barn side. And the smaller holes are probably 18 inches out from the wall. The biggest hole had 5 birds piled on topof it. This is was our baby rooster: This hole is about 18 inches out from the barn wall...and on the other side of the fence that you see is a 3 foot wide x 1 foot deep concrete slab. The hole's other side is in the barn: This chicken was pulled out of a hole in the ground (you can just barely see the hole to the left and slightly above the chicken's head) that was only wide enough for it's head and neck (all feathers are gone from the head and neck - looks skinned): Thank you for your help!
