The best thing to get a good herd of deer is to manage the deer that you have feed at least 12 percent protein feed ,an supplement with corn .Feed all year round not just when you think they they need it, feed more protein during October thru June because that is the time they are supplanting there young. When you watch them i would not shot any deer that is not at least three year old or older. Shot spikes at 2 1/2 with horns at least 6-7 inches long. At 3 1/2 yrs shot any cull bucks That you don’t want your off spring to look like,there are different options on 3 1/2 year eight pointers . You can go to different web sites and stores to get charts that will help you how to age deer. PS feed good mineral blocks also.
