RE: spike bucks
Like Chris H said, most are yearlings. I had a pet buck that was a 3" spike his first year, a 6" three pt. his second year, then went on to be a 100" class 6 pt. the rest of his life. If the spikes are 6" or less and the deer appears to be 100lbs. or less, it is probably young and best left to mature. If it is 130lb.+ and has spikes that look like main beams, it is a genetic spike and you need to take him out of the gene pool. A few years ago I took a 3pt. that with a 17" spread and weighed 190lbs! I'm still trying to get his offspring culled out.
