Different horse thing aside, make sure you are able to handle the youngling as they are. Unless you ride with a trainer every ride or have the experience yourself greenies can really test your patience and drain the joy out of riding if you're over horses. Not saying you are. Just speaking from experience with my Palomino Cougar. Got him at 3 and was WAY over horses. We learned together, but it was not always an enjoyable process. I've had him five years and have learned so much because of him, but if I had to go back I would've gotten something different.
