Wait until he shoots a bull. He might think it's bad as soon as he walks up to it.
Just remember with any game, especially on hot days, get it cooling down as quick as possible. Keep it clean and get the hide off. I helped a guy out, who's meet started turning green, cut the souring meet off, separated that meet and wiped down the blade of the knife after each fillet of meet we removed. I was able to save most of the meet for him. The green can spread very quickly, so only use this approach on stakes and keep it away from any grind. A butcher won't touch it, if it spreads across the animal usually.
