Sorry I deleted this post a while back (or tried to anyway). I had a very bad migraine and didn't feel like arguing about how well or not my hardware cloth was installed. The coop was properly reinforced right after the predator broke in. I really only wanted to know what others thought could have ripped through the actual cloth itself. From the replies I got below I am guessing it was one of the neighbors dogs. I just didn't think a dog could tear through hardware cloth like that! I was guessing maybe a coyote as I've heard them in the distance but never seen one. We've also seen a bobcat on our property once. I never found any scat near the coop. I don't think we have bears in the area. Anyway as I've said our coop has been properly reinforced and we haven't had any other issues. All my chickens are safe and secure and only free range with human supervision due to the large population of hawks about. Thank you for all your guesses on what could have done this. I have just always been curious. We will eventually get a game can to see what all lurks around our land in general. Going to try to repost the picture of the tear in the hardware cloth that was ripped.
