IMHO, I would have shot the doe. Every doe I see during hunting season has fawns with her, so it would be very tough for me to find one on her own. For those of you who say the will be kicked out in 2 weeks, in my experience even during our regular gun season Thanksgiving week, the does still have fawns with them.
I agreee with the general consensus though that if you feel good about the decision then you made the right one. We are all different and as long as we are safe and legal it is our choice to make. Nobody else has to live with it after that fact.
