In this case, you may be able to store the small bales inside a barn to preserve it. They can sometimes be pickier than cows or horses and consume the hay slowly. You may be able to sell bales to horse owners, pet shops or people with small herds of cattle. The baling of hay can be mechanized with a large baler, saving you time. These balers require a significant amount of investment in equipment. Large circular bales will also reduce the time it takes to feed. They are larger than square bales, so you will need to roll out a smaller number of them to feed your livestock. You can cover the hay with tarps, wrap it partially while you bale or arrange it in a stack so that water can pour off the top to avoid spoilage. Round bales are denser and more likely to combust if baled when wet.

Consider a small square baler if you have a small operation. Use square bales if you keep goats and sheep. Pick small square bales if you want to market your hay to small livestock operations. Opt for large circular bales if you have a large farming and ranching operation. Choose circular bales if you must store the hay outside. Go for large circular bales only if you are able to cure the hay correctly.
