Where they lay. I have watched deer eat next to a bleeding deer I just shot, and other times deer enter an area where a deer is down and dead, and pay no attention to it. I was gutting a deer, and had a buck walk up to see what I was doing. I shot him at 15 feet.
Deer are stupid, mostly. They don't cross the road at cross walks, have not learned to fear motor vehicles in 100 years or seem not be afraid of blood.
