So the "horns" (I know they are basically hair, not bone like a deer) will come off if I just hang it to let the meat rot off? Or might come off? That'd suck.
Yes, they are horns - not antlers. They will slide off. But they the animal as to ferment a little to let it happen. Put it in a plastic bag and this will happen easier and quicker with no other problems. You may find a pile of maggots after a few days if you don't skin and trim that head asap. The maggots don't really matter, but the process will become "icky". It just doesn't have to be that way.
The bucket method is called anaerobic maceration. Next to a big, established beetle colony, it's the best way to do it.
