Double lung bye bye doe IMO. The "fawns" (yearlings) will live to be a momma someday too. It's not like they have emotions about it.... I assure you they will not go back to their beds and mourn the loss of their mother like humans would. Also, it would probably help them grow up and learn the ropes themselves a little quicker. Their instincts as an animal will help them survive just fine.
But, ultimately if making that decision made you happy and you feel good about it, then that's all that really matters. Like someone else said hunting is a matter of personal choices. Good luck on getting your first deer with a bow.
One question though: If you saw a giant 10 pointer walking around with a spike and button buck at 15 yards would you pass?[:-]
