We've been having a coyote visitor to our coop the last couple weeks.... Seen the tracks but not the mutt! So far, hasn't managed to dig in (cement for a 12 inch barrier works it appears) but it makes me worry having him around. Coons haven't been bothering us after we redid the cages and cemented, and haven't seen possums either. Snakes are a different story. I've killed two rattlers back around the coop area, and one under my house. *glares* I don't like rattlers or moccasins!
