I love shooting yotes, but I do only be I love to do it. I am not trying to save my deer herd. I am sure they pick off a few fawns every year, maybe the 87% number is evern correct. I guess the way I look at is, here in Illinois the herd continues to grow every year, having the yotes picking off a few fawns here and there is natures way of keeping itself balanced. If you want to shoot of few of them for the sport, have at, but don't kind yourself and think you are saving a herd.
