LOL, I see the world a lot of ways, through rose colored glasses is certainly not one of them

Mayhap you are reading too much into what Cherie posted?? Nowhere on there does it say that they will be attempting to rehab the potentially useful horses on the exact same property as they are butchering the others.
Also, you are not the only one here with horse experience. I've had horses my entire life, my father was a trainer, I am a trainer, and I come from a long line of horsemen. No, I am not some naive little teenager from the inner city who's seen "spirit" too many times.
Yes, their proposal is
completely realistic...if they can maintain the budget and funding for it.
More than likely, it will be run similar to the cattle industry. Feedlots where horses are fed back up to a healthy weight, treated for any injuries/illnesses, then (when they are deemed fat enough for slaughter but unfit for life anywhere else) they are transported to a slaughter house that is off site. It would be my guess that likely, the re-training facility would probably be located on the same site as the feedlot. The SH would be a completely separate facility on separate property where the animals would have to be transported
to.
