Although not a homebred, I did buy Capi Rossi when he was six months old.
Here is a photo collage of him growing up over the years. I raised him, started him, presented and got him approved CSHA and CWHBA and took him showing... he is the definition of born broke! He has been gelded for a year now, but I am very lucky to have his only daughter, Haven, to raise and train as well!
I can tell you it was not an easy decision to make... I sometimes wonder if it was the right choice... but with three years of having him available to the public, the highest licensing scores with the CWHBA of his year, having an age appropriate competition career and thousands of website hits resulting in only one outsiding breeding... I just couldn't justify keeping him a stallion for maybe one or two mares a year. Then there was the money it was going to cost if I wanted to try for more mares - between getting him out and seen, with a strong show record, an appropriate marketing campaign and then some foals on the ground to show what he can produce...
It just made the most sense to let him just enjoying being a horse and make his hunter career be that much easier for him.
