I agree with Tiny. Is he still growing? By his conformity it almost looks to me like he's still in build, which could be a part of his "wonky" issues. His hind right doesn't look too horrid to me (in the first picture it appears he's turning toward you, which may aid in making the leg look 'crazy').
For example, I almost bought a 3-year-old gelding named Dixon
. As you can see, he's clearly still in build, judging by his age and his high rear end (which generally suggests there's still some growing to do). It was the same way with the gelding yearling Thunder Wolf
, who now -- at 5 years of age -- has evened out as far as height of rear/withers has been met.
