Honestly, I'd be looking for a new farm. It sounds like they're taking advantage of you. I just left (as in yesterday) the farm, BO, and trainer I've been with for five years because they decided not feed, water, or care for my horse. He was on the thin side (price adjusted accordingly) when I bought him, but he lost 100 or more pounds in a month. So he's now at a barn with an equine nutritionist as a BO.
It would be MUCH easier to find a new farm now and then buy a horse rather than buying a horse, having it lose weight, and then having to leave. Trust me. This feels like a really bad breakup.
Here's some more info on Noah, btw: Code Name Noah | Nearaway Farm
