I am working on my run, and the main part of the run is 2"x4" welded wire, with 1/2" hardware cloth on the bottom 2'. However, I have just hardware cloth, without the welded wire enclosing the area underneath the coop. Is there any danger in this, or is it really strong enough on its own? I suspect our main predators here would be raccoons and skunks. It would be a pain to reinforce the area with welded wire, but it could be done if needed.
