Auto Butcher

A machine that harvests nearby creature corpses on its own, using a hatchet or pick kept in its inventory. Yields match what you'd get harvesting by hand, including the difference between hatchet and pick. Tools wear out with use and the machine stops when there are no unbroken tools left to use.

Collected resources spoil at a reduced rate inside it, but only hatchets and picks can be placed in — anything it gathers can be taken out and never put back. It's a harvester, not a refrigerator.
