Hi, everyone! I have a small chicken coop at my city home. I'm pretty sure I have rats here. I've noticed some holes going in and out of the coop and have seen one at night a few times, but never during the day. They don't seem to mess with the chickens, they're only after the feed that they scatter around the run with their messy eating habits. I'm thinking about getting one of those electric rat traps and somehow trying to tighten up the bottom of my shed that the chicken coop is attached to (expanding foam and concrete, maybe?). I'm starting to think they're living under there. Anyhow, today I noticed a different sort of hole next to my fence and going underground. It was different in that there was lots of displaced dirt piled around the hole. I've attached a picture...is this a rat too, or do I have some new predator on my hands? The hole's about 3 inches in diameter. Thanks!
