I had my friend check the registration papers on his 2 horses that are full siblings to my 2 year old. ACPS records the 2 year old height and the height at transfer. Both of the siblings were 14.1 at 2 years of age, according to the paper work. Now the mare is 6 - and you can see that she is starting to mature and she is 15 hands and the gelding is 5 and 14.3 hands.I think this particular line is very slow to mature. I can see the wither development in the mare as she continues in her training.
My filly, on the other hand, is 13.2 hh at 2 years of age. Probably 13. 3 hh on the butt. Thats a big difference to me. She looks just like her sister did at 2- butt high, big head, no neck, etc, except she is shorter. For the record, I owned the sister when she was a 2 year old… so I am the one that measured her for her 2 year old height.
Anyway, just interesting how lines develop and the differences between individuals. I think I am going to do the string test tomorrow just to see where it falls, even though I have seen what Goodpony talks about in wither development.
Thanks Small Change, for letting the topic digress;)
