As far as shooting the fawns. I think you'll find most biologist or deer managers will tell you if you're trying to get control of a herd that is way over capacity, shoot anything that's brown. Get the numbers down to a manageable figure and then you start trying to control the herd for your desires. First thing.... kill them all within range. Now if you're happy with your herd you still have to shoot quite a few to keep it under control. At that point I'd steer clear of fawns because TOO many of them end up being buttons. You're better off taking an old doe who will probably have two where as a first time mom will have one more than likely. You see a young deer running around alone at this time of year it's more than likely a button driven off by mom or a bigger buck looking to make love to his mom.
