Can I ask a related question? What if you can't get hold of enough good hay?
Like the OP, we've really struggled to buy hay this year. I can get some from last year, but it's not great quality. However, would it be ok to use that, and to supplement with more hard feed than usual?
Is that ok, and if so, how would you go about it? We do have quite a lot of grass still, since we're understocked.
