Straw - We bought big rectangular straw bales (they look huge to me - not like the small square bales of old you could lift) in a nearby town and stored them.
Hay - We put round bales in the pasture with heifers as a supplement. (I also couldn't lift these, but I only ever see them one size.)
Speaking of bailing (haha), I'm going on a trip with some friends. Kris will be farming as usual. See you soon!
