From Texas,,, I have wounded a hog and witnessed other hogs turn on it and eat it while still alive. When I kill one, depends on what the landowner wants. 1, take the carcass to a specific area and I do my work on it. Leave it lay? That almost never happens. After moving hog or hogs to specified spot, I run my knife down the backbone. Edge facing outward. Then skin enough to expose the back straps and one ham. Sometimes I make a cut exposing the shoulder or at least part of it. Why? Birds can't get through a hogs hide very easy. And coyotes can see and smell an easy meal. You say but I really don't know of any buzzards or Turkey vultures in my area. Then split the stomach open. Coons will take care of this.
Did this once in the Edwards mountain area and a little later,,, maybe 1-2 hours it was gone. Stripped to the bone? NO It was Gone!!! Mountain lion took it. I would not have thought that.
During guiding hog hunts in south Texas, a man shot a pig at about 11:00 pm near the ranch road. I drug it off and left it next to a tree line. The next day, Before sunrise, I took the hunters out to their perspective blinds. The land owner said we needed to go ahead and move the carcass to the bone pile. I replied that I would get it after breakfast along with the mornings take. I didn't want to make an extra trip. As we gathered everyone for breakfast, we headed past the carcass. I made the comment that if I did the skinning routine on the animal, I would come back after breakfast to see the results. The landowner was still skeptical, of all this. Quickly did the magic and right at 2 hours, myself and the landowner, came back to retrieve the carcass. No less than 30 Turkey Vultures were on it, and it was almost clean bones. Course the head was still intact. But it was a light haul. When I have done this it makes a good bait pile for coyotes and coons at night. Birds will work it in daylight.
Try it and let me know how it works for you.
