Dog/coyote proof chicken tractor?

[max13077]

I just went outside to let the dog in and heard a bunch of coyotes down over the hill in the woods. Made me think they might come up here. How thick does the fencing on a chicken tractor have to be before dogs and coyotes can't bite through it? I'm building one in a couple months.

think in reverse. How thick would the wire be to keep them in. I saw a puppy chew threw hardware cloth. He was crazy. I would get the welded wire like the 2X4 inch type and line the inside with 1 inch chicken wire to be sure. The predators if they are hungry will work at it even if it hurts them. jean
