So I brought chance into the barn last night to groom him, and noticed that he has grown another inch, maybe 2, since I last measured him in October. This means he is now pushing 17hh, and is 6 or 7. He is also about 2 feet thick in his chest, and it's not fat. He is a purebred thoroughbred, was trained but never raced.
So what I want to know is if this is normal, and if anyone else has had this happen before, or is he just a freak-horse?
