To me it depends on how old the fawns are. Sometimes I see fawns with does that you can still see the spots on. If the fawns are 2/3 grown however I may take the doe or the fawns either one. All fawns are not born at the same time. Some can be two months younger if they are born late in the year. Besides with four and a half months of bow season there's no need to be in a hurry.
