Any does with fawns we let walk, as our winters are more harsh than most across the US, and them little guys need their mommas during the difficult season.
as soon as does are bred, they drive off their fawns. not shooting a does because it has a fawn with it is rediculous. the fawns are fully self suficient by fall.
if you have too many does, the only thing to do is shoot them. young, old, whatever. get your buck to doe ratio in check
