The '''Hay Hopper''' is a [[Tools|tool]] that is provided as a standard item in [[Barn]]s and [[Coop]]s when those buildings are constructed. It cannot be picked up or moved. Its purpose is to move [[Animals#Grass & Hay|hay]] between a [[silo]] and the player's inventory (backpack). Its commonest use is to access the hay for distribution as food in a [[barn]] or a [[coop]]. But if the player buys hay or otherwise acquires some (by gift, for example), and uses the hopper while holding the hay, the hay moves from inventory into a silo, as long as there is enough capacity there. Hay can move in either direction.
