Do mixed-ranked Dens actually work? in Cub Scouts Posted February 13, 2019 That’s essentially what we did for the exact reasons you listed. Unity of the den was a big one. In addition we were able to patch some areas where our Boy dens didn’t have great den leaders with parents of girls. The final issue was that it made the girls look like this odd group we added to the pack.... as each boy den was a single grade (6 dens) plus a collection of multi aged girls. All packs in my area who I have talked to and added girls have done the same. Our council and district are aware as are all of our parents. No concerns raised.
