I agree with Txhunter. I am also from Texas, I have never seen a full grown spike. There are probably some that are full grown and are spikes but I have never seen one. Usualy if it will be a small deer it will not stay a 1X1 but maybe go to 2X2 or 3X3. I agree with the middle of the road aproach. Shoot the older spikes but always remember, You kill it you eat it in term of non-varmits, pests, etc. If you kill and dont eat than you start almost poaching, its a bad habit and anyways the meat is good.
