I assumed your no dig hardware was on the outside as would be your stone. My freeranger hens can kick mexican river stones 4 inches around looking for bugs and crickets. My hardware cloth has been absorbed by the lawn and is cut to 2 inches once a week. You just can't tell it's there.
don't bother with rocks, the hens will just dig them up. Use hearty metal lawn staples and just use them to tack the cloth down. The grass with be up and through within two weeks. The thatch will totally cover the wire within a season.
So horrible. But I think it was a fox. Don't bury the dead on the property, you can't bury it deep enough and he'll be back for the parts and just dig them up and the smell, that you cannot smell, will bring other animals too.
GIANT HUGS.
