I've noticed that roosters will drop one shoulder, droop that wing and scoot sideways fluttering a little in order to....move the hens around? My sweet little Banty does it to his hens when they get too close if he's eating and shoo them away. My RIR used to do it to me before he launched an attack. What exactly is this behavior for. I mean, I can guess it's a dominance thing right?
