I don't shoot them. I do everything in my power to distinguish between buttons and does. If I'm not sure, I don't shoot. I'm fortunate enough to not have to worry about an earn-a-buck situation where I NEED a deer to get that buck tag. I think part of my not shooting is growing up in the U.P. where shooting does was not even an option, so I never even thought about shooting a doe, let alone a bb, until I moved to IL. Now that I target does in the early and late season, I just make absolutely certain that they are female.
