We have a 10×10 chain link fencing for our turkeys. We've got that green temp fencing on top for a cover. The other day I went to feed them, and the black ones head was outside the coop. You could tell there was a struggle(due to piles of feathers on both sides of the fencing on either side of a hole in the chain link. Outside was the head, then about every 5 ft was a huge pile of feathers. Then about 20 yards off in the field, was another pile of feathers. No sign of any body at all. Can you please help us with pin point the predator. Thank you!!
