We had our flock destroyed last night. We had two large roosters and 7 jersey giant hens. Something came and killed all the chickens and two large hens (the one hen apparently put up a fight and had a predators eye laying next to it), our fence was bent over (like something large got in), two chickens were dragged outside of the fence and the rest were dead inside the fence. SOme were ripped apart but at least half were not really eaten at all just killed. They were not burried or covered with anything. Our chickens are in an elevated chicken coop (and unfortuntly the door was open (must have opened with the loud wind that evening). What would kill them all and leave their carcasses? All the heads were on the chickens as well. We live in the poconos of pennsylvania off a main road but there is a mountain and hills nearby. We originally thought minks (because there are rivers nearby)- but with the bent fence and the chickens dragged outside the fence (there are no other holes large enough to drag out of) we were thinking something larger. Also minks couldnt get into the coop because its elevated i would think.....Any ideas? We have not seen any racoons or predators around during the day besides a neighbors cat (which is about the size of our rooster). The ground was frozen so there were no footprints or any evidence. Thanks! This was our first flock of chickens ever and are a bit devastated and want to make sure we dont make the same mistake again (and will fortify our fence and coop much better)-but we'd like to see what we are up against!
