How old you count as yearlings as they grow quite a lot in their yearling year? My boy is 19 months and is 14.2/14.3hh should make 16/16.1hh. Hope this helps
My 9 month old yearlings are 14 hands 14.1 hands and 14.2 hands high all to make around 16 hands when fully grown.
My 21 monthe olds are 15 hands (to make 15.2) 15.1 1/2 and 15.2 1/2 both to make around the 16 hand mark
LOL Sally, I've not been sure how to answer this, as H is technicaly a 2yo now, even if he is only 21 months old. FTR He's approx. 15.3hh atm, should make 16.2hh
