My father-in-law always bought the small square bales of Alfalfa. I added it up for him what cost he has in the small ones,now he buys the big square bales.I do have to unload them for him but he has a big barn to store them in. He has two plastic bed mats that go in a pickup set up on ground were I can put one bale in and when he bust it open to feed his sheep,the good stuff dont get in the dirt,no waste this way. I usually just feed round bales to my cattle but do put up around 50 squares,case I have to keep a cow pinned up in corral or something. But for those that dont have a way to move round bales could always get one of these..
