The hardware cloth on my older coop is rusting away/no longer attached around the bottom in some areas where the skirt bends at the coop… but I guess if something digs it will still be digging on top of the skirt part… I do still believe in having the skirt but just wanted to let everyone know that it does start to rust… even though it is galvanized. So adding rocks or stepping stones would help reinforce it. My first coop is 7 years old and the add on is probably 5ish… it definitely needs maintenance…If you have rocks on your property, that's what we mostly used. We have a lot of rock. Free dog deterrent. I'm not home for a few days or I'd share a picture. Hardware skirt with rocks to anchor it, would work even better.
