RE: How long should I wait?
Congrats on the kill!
I like to educate as few deer as possible. Was the BB alone? If he was with his mother and another yearling, I'd let it settle down for a week. If he was alone, he was the only one who saw you. Hunt it again. In my experience a blood trail and most of the time even a gut pile have no effect on the other deer. But I always wonder about the scent I leave when I drag a deer out. Is that alarming?
How many times did you hunt it before you connected? That may be the real factor. If you hunted it every day for a week, it may need a break. If it was the first night, maybe not.
Bottom line, your comings and goings are more disturbing than animal parts/scent left behind after a kill.
