Thanks everyone for all the help. I'm not the owner of these horses, just trying sell them on the internet.
The owner/seller is a knowlegable College educated (Equine studies) lady, she trains both horses and people and keeps her stock healthy and up to date on vet/farrier/wormers.

As for the Friesian-cross, her Mom was a product of a Friesian Stallion jumping a fence. Her mom came out looking like a 15h Friesian. They bred her to th TB stallion looking at getting a dessage/eventer horse, however since the hay issues have come up here they decided to sell the foal.

As for the stud she's selling him cheap because he's older and not producing as well. I too think he'd be better off as a gelding, but would gelding at 15yrs have much of an effect?
