EVA, they said that his testicular size was more than adequate (an indicator of potency/breeding maturity), so I imagine they collected him to test him for cooling and freezing, and it proved to be quite good. So now, they can collect and ship him as a 2yo, which many breeders do. I waited until my stallion was a 3yo before being collected, (recommended to me, although we could have at 2), and that's what I did. They're all different.
