wild chickens or grouse
hunting chickens is easy enough, just get a 4-10 shotgun or 22 with a scope and aim for the head. step on the wings and pull on the feet to skin them.
butchering pigs is fairly easy with 3 people, get them in a corner and shoot with a large powered riffle in the head. an electric fence will usually hold them good and provide enough to supplement their chop supply. give them asmuch as they can eat, usually good to put milk and leftovers with the chop aswell. chain each leg to the forks on a tractor cut off the feet and head with a sawsall then pull the guts using 2 fingers and a knife cutting from the inside out being careful not to damage intestines skin/cut pig in half and hang in cooler until ready to package.
