fawns......... well.
I have shot small does which we call skips around here. Meaning you usuallly skip shooting.BUT sometimes it happens. I can say I GENERALLY won't shot them if they are with the mother or another deer. If it is by itself.... still depends on what time of the year/season.
SPOTS.....nah Get more meat from a Big MAC burger.
If it is hurt / limping.....gotta rethink it.
