I hate clay! At least it's really wet, about as easy to dig as it's going to get, but ditch digging was not so fun. Here's what I did today:
It's probably 6-8" deep, I know it should be a foot down for the hardware cloth. But I'm wondering if that would be far enough if I also partly filled the space with some large gravel (or river rock) and went out about 6" and a few inches deep with the gravel/rock. I wanted to have some around for drainage anyway, will it help deter diggers, too? There's the hen house within this structure but they'd just be locked into the greater structure, not into the hen house.
