I would guess him as only a 3 year old in Georgia. That is in Brooks county right? I believe he would have a little more defined belly if he was 4. I am no expert and they can fool you during the summer. He is not a 2 year old for sure. His chest is too developed for that. It is super hard to let one walk like that in Georgia but if you got good nutrition, which I believe you probably do, and he makes it another year, he would be a Booner next year. That is my goal on our land anyway. I am trying to let the young super stars live. That's the only way to get them big. Good luck but I would love to see what he would look like in a year.
