It's hard to tell in that pic, but does his neck seem a little short? Seems like as thin as he is his neck ought to look longer.

I'd have the vet to him before you start feeding him up too heavy, or worming him.

Maybe, but he's angling toward us too... and when they're thin they never look like they have a good neck, they lose the crest and look ewe necked even when they aren't.
