We do round bales now as they're much easier. We pay $60 per round bale and this last one was gone in a week

... but it was a nice cut. The last one we had they left about one square bale left, but it wasn't that great of a bale and we were surprised they ate that much considering it got rained on.
Square bales were too much of a hassle, especially to keep weight on our guys. They got 2 - 3 flakes per feeding, but it wasn't enough so we went to round bales. I think Orchard/Timothy mix is around $4.50-$5.00.
We paid $8.00 for one square bale of straight Alfalfa from Alabama(I think) when we lived in Maryland, that stuff was bright green.
