They are not really strutting. They are drawn to a food source and just happened to show up together. usually this time of year you don't find gobblers and hens togther, I don't think. I'm not a tukey hunter and don't know a heck of a lot about them. But I see them together in the yards around here but not often in the woods. Best I can figure, there are about 200 birds in three or four flocks and they are destructive as all get out.
they also pose somewhat of a danger. one of my neighbors had to build a cage for his grandkids to play in. I told him I would come over and flat blast the bejeesus out of them any time.
