That'd give a meaning to concealment, like when you use the skill, you get a speed of 0.3 or so, and you can't switch equipment, neither wear shield, helmet or mail. This way, you can approach a deer without frightening it, and kill it with a well-placed **** or, if you're coming from behind, a blow. There could be small animals which will run at speed 10 or so, or larger ones which will attack you quite hard, which would be larger, drop more food and maybe take 2 or 3 hunters... Being able to place traps for animals (nets or slings) would be nice, and crafting stuff for houses from the droppings would be fun, too.
Another idea, why have them drop items? make it so that you have to carry the corpse to a certain house (maybe 2 carrier for a big one, or 2 halves) where you can seperate certain parts from it, like legs, liver, heart, skin or antler...
