Antlered does have exceptionally high levels of testosterone and will rub the velvet off their antlers once they harden, just like bucks do. The Eagle notes that about 1 in 10,000, or even as few as 1 in 100,000, does grow antlers. In the piece, Keith Sexson of the Kansas Department of Wildlife, Parks, and Tourism, estimates he has heard of fewer than 15 antlered does in the state in the past 50 years. The Wall Street Journal points out that in the South, antlered does seem to be just as rare, and estimates that only four were killed in the entire U.S. in 2014. The Journal notes, however, that one of these antlered does was killed in Sedgwick County, Kansas—not far from where Jerika Francis killed her deer.
