So we have a coop, that is predator proof for city predators. I let them free range while I am in the yard and then they go back int the coop, we haven't built them an enclosed yard yet. DH I have discussed at length what is best to use since we know chicken wire is no good for keep things out. DH brought home some 2x4's for the posts and 1/2 inch 19 gauge hardware cloth for the wire meshing. Is this good for keeping city predators out? so far as I have heard our biggest nemesis will be squirrel, but I am sure raccoons live around here somewhere.
