I'm not sure if this is in the right place or not but please feel free to move it if not thanks. I have a question about an 11 year old gelding and what is on his passport. He has a stallion number and is registered with the Highland Pony Society. Is every colt born that is registered issued with a stallion number or is this indicative of him being used as a stallion prior to being gelded? Is quite bolshy/pushy/bargy if you let him.
