I disagree. Not dying at all. In fact' I could sell every small square I used to make. I don't want to. Too labor intensive, hard to store and then the getting paid an equitable amount is the deciding factor for me.
Horsey people will always use small squares because they lack not only the ability to handle rounds (equipment and infrastructure) to deal with rounds and besides rounds are wasteful for a horse owner so there will always be a market for small squares. Not going away so long as horsey people exist.
I don't know of one horsey owner around here that uses or wants round bales. They all want small squares, they all want premium hay and none of them want to pay for it either.
I got out of it because the grief factor outweighs any benefit.
The stuff you bale (mostly grass) isn't what they want anyway. Cattle don't care, horsey people do.
