Because the tribes here are relatively small and all have roosters normally, it's the roosters who break up the hen fights here.What's more, there seems to be a *peacekeeper* amongst the girls who is the oil on troubled water when disputes start getting heated. In my flock it is Luna, a Favorelle X. She is a calm middle order girl who seems able to avoid being on the outer with anyone but anytime someone is really getting bullied she steps in & puts the bully very firmly in their place & everyone accedes to her authority in these matters. It is fascinating!
Most of the hierarchy pecks hardly disturb the feathers despite all the fuss made by the recipient with the chickens here. An advantage here is there is plenty of space to avoid conflict even to the point of moving coop on a couple of occasions.
How anybody can ever dismiss chickens as stupid creatures is completely beyond me.
