Well, the Thriller looks like he could be pretty square and sound, but the pictures really limit anyone from making any valid judgements. That is likely why you have seen no reply posts.
Let them grow a few more weeks then take some good side profile pics. Try to avoid taking the shot when the calf is looking at you, as it makes it darn hard to evaluate the neck and front.
Better pics and older calves will make it much easier to evaluate them.
