My coop is solid, it's a bomb proof building, nothing is getting inside after lock up. But I can tell that at night, something is messing around inside my run which is a 6ft. chain link dog kennel partially covered. It's clearly used a wood pile I had temporarily leaning against the chain link to get out (so I just removed all of that.) My HOPE is that with no food for it to get, it will eventually go away but I'm here to hear how people detour them. I have barking dogs that go out at night if they smell anything through the window and I have a live trap, but I also have 3 feral cats that will wind up in the trap..... Also have a boyfriend with a shotgun but he actually sleeps at night.
