I think it really comes down to your horse/pony. My young one is 3 and 1/2 now and still very immature. He still has a lot of growing to do and is into everything... I think you will find from previous posts on Stockies that the most common age for starting is around 2.
My boy leads, lunges, ties up, has feet done, had a roller on etc BUT he is not broken yet and I will not do so until he is 4. Just my choice, but I feel he is certainly not ready mentally or physically just yet.
Go with your gut feeling with Lacey - maybe start small and if she copes ok, give her a new task and see how she handles it. Best of luck with it all, keep us informed on her progress, it's very exciting!
