I think the question was just answered. It should be extremely rare for this to happen in the wild though. Most bucks begin antler growth well before fawns are born. Studies have shown that there is a small increase in blood testosterone levels as antler growth begins. That must mean that the fawn is born very early and quckly becomes sexually mature. (doe fawns can be sexually mature andbreedduring their first winter) Also, bucks will usually take minerals from their bones and devote them to hardening antlers. In older animals, it is believed that these minerals are deposited the previous year. Therefore, for a fawn to use energy and minerals for antler growth rather than body growth, it must be in extremely good condition and have plenty of very high quality forage. Maybe they are carnivorous deer that eat bone fragments... kidding. Anyway, I have seen yearlings (those between 1 and 2 yrs old) with 10+ pts.
