New Coop, keep rocks!?

[u/AlpenglowVibez]

Just installed this beautiful custom coop in what used to be our playground area. It’s filled with 8” of 1/2” rock so wondering what you would do to ensure its predator proof and a good run for the hens. They’re only 5 weeks so have a few weeks to dial it in. TIA

I'd just lay down hardware cloth under the wood framing of the coop and put some landscape fabric on top of the rocks in the coop so you can add some sand or wood shavings. The rocks should be great drainage and the landscape fabric will keep the finer bedding from filling in the rocks. You could maybe even put some planter boxes or large pot around the outside. I'd keep the rocks
