Late season, when the bucks group back up, and doe groups hang together, button bucks will usually hang together too. Button buck groups usually 2 or to 3 together, will usually be the first ones to hit the food plot. Late season, I always try to shoot big does or yearling that are following a doe. Most likely the yearlings following closely behind a mature doe are doe offspring. We have always shot at least 2 does for every buck harvested during the season in unit L. Seems to keep the heard looking healthy.
