Well, I either have a coyote or a neighborhood dog problem. That's the only thing I know of that can tear through hardware wire to get to my chickens. Oh I'm so peeved. They were two of my favorites and gorgeous to boot. If it's either dogs or coyotes I'm going to have to redo my coops. I'm thinking I'm going to have to fence in an enclosure to put all of my coops in. And I will also house a Great Pyrenees.
