My little project this morning was/is putting down chicken wire on the ground around the coop. Honestly, as much difficulty as I've had putting it down (using garden staples), I can't imagine the ground would be very easy to dig in. But I'm hoping to minimize the chance anyway.
I also got some wood pellets, since that sounded like a nice bedding and run floor material. But the coop sits underneath a couple of big evergreen trees, and so the run is currently covered in needles. I don't see much point in covering the entire area in wood pellets just yet. I was afraid it would immediately turn into a big mud/poo pit, but maybe that won't happen for a while...?
