I only had horses as a kid. In a long story, we have ended up with five horses we rescued in december. All were body score 1-2. All now look fantastic except for one, a yearling stud quarter horse colt. His eyes are clear, nose isn't runny, eats well, wormed regularly, stools are solid. He is still at a 1-2 body score. Nobody else will take the horses and we don't have the money for a vet. All our money goes their feed and hay. Anybody have any ideas before we break ourselves with vet bills???
