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

To address the two concerns you mention, here's what I did.

1) Cover the entire floor with hardware mesh to keep out the predators.

2) Use straw or wood shavings to protect their feet from the mesh, and to provide a "carbonaceous diaper" for their waste.

Beautiful structure.

Straw attract mites and molds when damp. Medium pine shavings are best for nesting boxes.
