Little guys are extremely hard to evaluate. I'd wait a few weeks. I will say he seems to have great breed character. Nice roman nose, long pendulous ears. Otherwise, he looks high in his loins and short rumped. But, as I said, little guys are hard to evaluate. Again, more importantly WHAT ABOUT HIS DAM AND FEMALE RELATIVES?
I hate to sound like a broken record, but for Jr stock, that is the MOST accurate way to evaluate them as far as merit goes. The vast, vast majority of male animals are NOT breeding quality. We just don't need that many males, and almost certainly there are more worthwhile animals available. Not that it's always easy - they may live across the country from you, leaving you to practice AI to hopefully get the traits you want.
But, the vast majority of males should be prone to castration at birth, IMO.
I actually like your little brown buck. With good management, I think he may straighten up to be a very nice 3 year old. I find young stock and yearlings to change a LOT. Keep in mind breed ideals are based on a 4-5 year old animal, NOT a 1 year old. This is why we base our breedings on what parent and mature relatives look like - the POTENTIAL, not the appearance necessarily.
If you use a young animal, evaluate the productivity of that animal or its offspring. Unfortunately a full assessment cannot happen for 4-5 years, so a lot of breedings are based on guesswork. I have the opposite of barn blindness - I absolutely hate my FFe'rs and jr bucks almost by rule. I restrain myself because I KNOW they have the pedigrees to back them up, so it's simply their immaturity that needs to catch up. My least favorite rump when she was a FF, is now my most favorite back/rump and scores highly in LA. It's amazing what a few lactations will do for a doe, and a few years will do for a buck to really show their conformation.
