Bales that are stacked on edge will cure out better than those stacked flat because moisture will move out of the bale more readily. Also, bottom bales will not break as often from rotted twine or rusted wire exposed to damp floors.
Producers and dealers agree that in stacking bales, the direction of the layers should be alternated and bales should be stacked together tightly and level.
Producers who stack large round bales indoors report that bales stacked on the end cure out better than those stacked on the side. When large bales are laid on side, three or more high, the bottom ones become misshapen and hard to stack on the truck.
Stacking hay on pallets is one way to reduce labor and retain hay quality. Dirt or concrete floors can become moist and ruin the bottom layer of hay that is placed directly on the floor.
