Here is my setup. You can see I have these stone pavers as a foundation to my coop. The first one is held down by the weight of the coop, and then there is one more extending away from the coop. I'm hoping that nothing would be able to dig under them. We have some coyotes nearby (very suburban area), but I don't think they would ever wander into our backyard, so main predators are opossums and raccoons. The stones are fairly heavy. Anybody see any glaring problems with this type of an apron to keep diggers out? I originally liked the idea because it keeps the wooden base of the coop out of the mud and will keep it from rotting.
