I have not seen many bucks that had only one browtine keep only one the rest of their life. I have seen a lot of them get a second browtine. Most of them will not have big brows but they will have both. If I did not know what these bucks were last year I would keep them till next year since they are both young.
Good point. I probably should of asked that question in my initial post. Unfortunately I can't say what these bucks looked like last year, but I was wondering if others had seen bucks develop brow tines as they matured where they were missing as youngsters.
