I havent seen a lot of calves out of him...the ones I have seen profiled really nicely and looked great with a lot of shape while standing still. But all the ones I have seen tended to have trouble on the move and it all seemed to be in the hip joint. I dont know that its necessarily genetic, because the first thing that always popped into my mind was they moved as if they had been injured, like I said only seen a handful of them, but still has my attention since they all seemed to be that way.
