I put all the guts and left over bones, heads etc on an area of my land I refer to as the "graveyard". I believe in using all the parts of the harvested deer. By throwing out these parts I provide a food source for bald eagles, hawks, other suet eaters and of course coyotes. I just make sure that there are not left over bones that might puncture my Kubota tires before I mow this area for the first time.
