Hi, I'm very new and planning a coop. I keep reading about burying wire. We have very hard clay filled ground. I really don't want to dig this down 2'.... I was wondering about using 18" inch concrete pavers under the base of coop and border of run. Thoughts? We have coyotes in the forest nearby but I'm in a suburb and they have not come near the homes before. Tons of raccoons too but I'm hoping they're satisfied with dumping out my compost regularly and eating that!
