Anyone observe their chickens breakup into distinct groups that seldom interact with other groups. The groups I am thinking of are based on adults; a dominant rooster with a group of females and usually a couple subordinate roosters that move about periphery of group. Such will not usually occupy same place at same time and will roost in different locations. In my case they roost in different buildings. The young ones do something else once they leave momma with momma usually going back to her group.
