I would bet that he is definitely a yearling, especially if the photo was taken recently. Older deer tend to grow earlier and end their growing period earlier than the younger bucks. Don't be fooled, just b/c he is a six point doesn't make him older than a yearling. I used to own a pet buck I raised that was a 13.5 inch inside spread nine point his first rack scoring 96", and he didnt come out of any special genetics. I have first rackers right now that are 8 points and about 13" spreads. Leave em grow a year and you will be suprised what he turns out to be. Last year I passed up a lot of buck with seeing about 3 good shooters out of about 11 diff. buck. Now that location is loaded with bucks that are at least 18" inside and really nice.
