I have 4 of 6 laying now. The top hen has been laying almost 6wks longer than anyone else. She's also bigger and definately the boss. No roos with them as of yet. If I go to pet the 2 who are not laying yet, they crouch and sidle away. The 4 who are laying including the top hen, hunker down and do the full on squat until I stop. Does this make me the top roo/hen? If so, is there some advantage to be gained?
