Wouldn't either the Mare or the Stallion from a very early age within their breed standard's evaluation's and grading, or throughout thier professional career's , have made some mention of Sickle Hocked if it was present ??? Same as Baby Hunter, he's got the clean bill now, we'll see what they say at the Standard's, I will be mentioning Sickle Hocked to them personally, if we're absorbing big costs to fly the experts in, better be getting the good's.
