So, I know that I've asked similar questions before, BUT: If I were to put hardware cloth underneath the whole run, how much bedding would I need on top of it? I know that usually a hc apron will be just fine for predator protection, but other family members are being paranoid, which is good, I guess? I am planning to lay down some mulch to start off a semi deep litter run. I will have a sand/dirt dust bath for them as well. How many inches of mulch do I need to make sure that none of my girls damage their feet?
