Didn't have any problems for three months then for the last week something has gotten in and killed two of my hens. After patching one hole and setting a trap I caught a huge racoon. It was too big IMO to get in the hole I patched. I killed it anyway but I was curious if that was the culprit.
Last night something got in, killed by biggest hen, dragged her body to the door and left her there with one leg chewed off. It appeared as if it wanted to take the hen outside to finish eating but the hen was too big so it chewed on her leg from the outside. The opening it got in was about 1" so I figured it was a weasel. I filled in that 1" gap. We'll see what happens next.
