I make my own - we have fields with timothy & orchard grass and a tiny bit of clover - it hasn’t been reseeded in too long. But I have easy keepers and grass hay is easier to put up than legume.
Buck22, you don’t live in NH do you ? I would love to sell my extra hay out of the field, rather than expend the energy and time to put it up and sell it out of the barn, but I have found that people just don’t quite get that when I say “hay around 3PM” I mean you need to be here to pick it up sometime between 3 and dusk. Not 10am, and not sometime the next day. After finding myself putting up 400 bales that someone decided wasn’t convenient to pick up after all, I stopped offering ‘hay in the field’ at a lesser price.
I like making hay, but it is a lot of work getting it from the field to the barn. I’m not a big enough operation to have a bale kicker and wagons.
