For me it depends on what I feel like doing that day. If I' m hunting for a mature buck only...then I' ll let them walk. If I want meat that day...then you bet, I' m shooting. We have so many does where I hunt, they need to be thinned out. I have no reservations about shooting does with fawns, sometimes I' ll shoot both. No button bucks though.
I read one time...a biologist said that in areas with overpopulation, the right doe to shoot is the one that stands still long enough to give you a clean shot. I agree
