I agree, drop em where they lay..death is normal process in nature so they are use to finding dead things or parts of dead things.

A quick story 3 years ago I was bowhunting Mule Deer, had 2 bucks feeding in a meadow the larger buck came into my lane/range, while the second buck was about 25 yards in front. I shot the buck he bolted maybe 40 yards then stopped and look back at the bush that just stuck him, the second buck equally stopped. Then the effects of the BH took on the buck and he fell, the other buck walked back to the dead one sniffed him, walked about 15 yards and went back to feeding. Only when I got up did the other buck decide he should leave!
