Hi - have any of you ever covered the bottom of your run with hardware cloth? I have a small run, under my coop, which I just repainted and is ready to go upright again. I used chicken wire in this way the last time, but it rusted out. It should not have been good for predators anyway. I never had any predators dig under the run except for chipmunks, although there are at least raccoons and opossum around. I use sand in the run, and the chickens love it! I really appreciate the easy cleaning. Hardware cloth should be more durable over time, but I won't be able to turn the coop on its side in the future as an addition is going on. Please let me know if you have ever used wire in this way!
