If you were to shoot all three you would have a buck sticker for this year, one for next year's archery, and one for next year's gun hunting. The DNR wants the population in your area to be greatly reduced, hence the earn-a-buck. You would be contributing to the containment of CWD. Plus fawn meat is tastey. If you shoot the doe first, the fawns will probably stay there or can be brought back with a doe bleat.
