I noticed that too, Kayella. I'm hoping that second sibling grows out of those posty hind legs and sickle hocks.
OP, another thing I want to say about this ranch...it seems like they put A LOT of stock in color. Every single one of their ads touts the horse's color more than its conformation or potential.
Also, I'd like to know exactly what their stud has done, as far as showing or competitive sports. If he hasn't done anything but be a stud because he's a pretty color, I'd be looking elsewhere.
That colt you're looking at is cute, but I'd have to see his dam in order to make a judgement call on what he's going to look like when he's older. If the mare is as average as the stud, again, I'd say pass.
