My grandfather used to recycle his dead chicken by feeding them to the hogs.
When a neighbour had pig pest in 1998 and werent allowed to move any pig off the farm untill the disease was under control, we had hogs everywhere, in the implement shed, and between the sheds in knee deep mud. At night you could hear them scream, if one of the hogs coughed because of pneumonia, they would sniff upon it. IF it gave no reaction, they would softly bite it. It gets worse when the other pigs start too, untill the hog starts screaming. My father had many sleepless nights because he knew the scene he would see in the morning: The hogs had plenty of food so they wouldnt eat their peers, but just bite it to death, skin was punctured and scratched, and the hog would be totally blue. Only if there was one hidden in the corner that would be around for 2 or 3 days, the meat was tender enough for them to eat.
With piglets you get the same: If you stand still for more than 5 minutes, even the weeners start sniffing, plucking, biting harder and harder.
Anyways, we prohibited my father to go in these temporary hog pens alone, with 80 pigs. If he would fall over because his boots sucked stuck in the mud, there is a big chance they push you over before you can stand up, and once you're down they start progressively sniffing, pushing, biting.
Didnt some mobsters have a pig farm for the purpose of making opponents disappear ?
