i don't know where else to go with this question, so hopefully someone has an idea for me. i live in the suburbs of philly and keep my six chickens in a coop surrounded by a 6'x10' chainlink kennel. after a run in with some coyotes over the summer, i wrapped the entire bottom two feet of the kennel with hardware cloth, as well as the ground surrounding, two feet out. i thought i had all predators stumped, but this morning i found hole, inside the run, about 3" in diameter. i searched the area around the outside of the kennel and found the exit hole four feet away, also about 3" in diameter. it's mid november and cold, so i don't think it's a snake. i don't smell any skunk odors and my chickens are unharmed, for now. i don't think a rabbit would purposefully burrow into my chicken run, and the holes seem too small for a groundhog. i'm baffled. does anyone have any ideas of what might be doing this?
