Gak! That is a truly GHASTLY injury! Yes, I'm interested in seeing it all healed up.
As for feed, when horses are getting high quality feed, you can sure see it! They can look "OK" on hay alone, but most don't look great without good high quality supplements, and enough exercise to really be in good condition. You can see it in their shape and coat, but also in their expression and energy level. Heh... I have an old Arab, if he doesn't Piaffe the first two miles down trail, I think something's wrong with him :~D
Bay's been eating regular sweet COB all summer, he was holding weight a little too well on his senior, but as the temperatures drop, I'll probably be putting him back on Senior for winter.
