I have game cameras. Anything that gets near my coops, get their picture taken. I have electric wire around my coops and pens because of a bobcat and a possum, concrete under my gates because of a fox and a skunk and heavy duty netting covering all of the pens because of an owl and a coyote that jumped over a 5' fence into a pen and killed some birds. The owl was a hard one to figure out until I put up a game camera and caught it in action.
