By the time the season comes around, the fawns are old enough to survive on their own... otherwise the game departments would not allow does to be shot. There are only a few instances that this is not the case, and that is in extremely over populated areas... where deer are being shot on kill permits during otherwise out of season times.
So I wouldn't skip a beat.. and let one of those doe fawns linger too long and see if it doesn't catch 100 too.
