The absence of any females is a good sign that they are somewhere in the woods birthing and caring for the newborn Key Deer of this season. The mothers hide the fawns for about a month before reemerging to join the others.
Notice all antlers have fallen off now. The males like to band and bed together when it is not mating season. This group probably is a mix of fathers, sons, uncles, nephews, cousins and brothers.
