Is this normal and why would they do this?? I have 10 chickens, 1 roo, 9 hens. Roo (Rosco) is a RIR, as are 3 hens, 2 are EE, 2 White Leghorns, 2 Black links. Hubby seen one of the red hens picking the feathers out of Roscos hackle, and eating it. He let this continue until she apparently pulled a tight one and then he just stood up and towered over her and gave her that look and she flattened out on the ground in submission. Is this just a grooming preening thing they do to each other like monkeys??? He is not showing any signs of baldness, and he is still the ruler of the roost.
