It’s a real problem if you don’t have any fuel for the backhoe. I’m thinking scarecrows. A little twine and a couple of crossbeams and you could have a marionette show for the kiddies. Some strings of lights and you have tasteful holiday decorations. After that, it’s tough.
Seriously, I’ve thought of hot composting, but you need a lot of “hot” manure, like chicken.
I once buried a freshly dead skunk in the middle of my compost heap, and at 165 F, it was un-findable after a couple of weeks. No bones or anything.
Just adjust for scale, and I can see this as viable.
I was told one time that the Turks use to hang bodies of dead thieves in trees around their supply depots in Korean and after which they didn’t have to worry much about other thieves from then on out.
I knew there was a reason I liked you. ;)

If nothing else, boil the bones, hang them at the gate and set an empty BBQ sauce bottle next to them. That should stave off most of the zombies. As Sipsy said, “The secret’s in the sauce.”
