I am building a 10x20 run. I am covering all sides with 1/4” mesh wire (maybe a bit overkill but want to be extra safe) however my question about keeping foxes and raccoons from digging under is if I can lay down 3’ wide chain link fencing around the perimeter (tie it into my mesh to prevent any gaps at the base of the run) and be confident it’ll keep raccoons and foxes out. Surely they couldn’t get through a chain link fence skirt right? Thank you for the help!
