I run into this quite a bit each season. For me, it usually comes down to the actual situation, and what I have going on outside of hunting, as to whether I take the shot...and which one(s) I take. I have taken does with fawns, I have also taken does and fawns together. Last week I had 3 fawns and 2 does come by at 15yds. I chose to pass all, mainly because I didn't have time to fool with a deer that day. I will say though, I notice myself to have gotten a little soft over the years and tend to let more does walk if they have fawns. I'd personally rather shoot a yearling that has not had fawns yet, if I have the choice. Bottom line, like others said....do what makes YOU happy.
