I watch my four 20 week old pullets. They fly at each other, chests out, hackles raised. Then they stand and give each other the stink eye. Then they go on pecking at the ground. Or they chase each other. Then go on pecking at the ground. I see the role of top-chick change hands. Except for poor Lizzie, my Welsummer. She never seems to move up. But mostly I think she's just more mature and above all the tussle. She's definitely going to be the first to lay. She does her own thing. It's hysterical to watch. So are they really fighting, or are they playing King of the Hill?
