I'm new to backyard chickens, so I found the following behavior quite interesting from my Barred Plymouth Rock pullet - Lulu. I have a flock of 4 pullets, each a different breed - all between 10 & 11 weeks old. While foraging in the backyard about 20-30 feet away from their coop and run, a small bird flew down and started eating some chicken feed that they had scratched outside of their run. Lulu ran over to the bird and charged it (head down) to chase it away. When it flew to the fence, waited, and then landed somewhere else near the run, Lulu again charged the small bird away. She then proceeded to stand guard around the run/coop and also chased off a dove that came to see what goodies it could find. The other chickens happily continued their foraging away from all the action and eventually (once everyone gave up on trying to get some snacks), Lulu rejoined the flock. Does this mean that she is in charge of the flock? She has always been the bossy, pecky one, but it seemed to me that my Buff Orpington was in charge of the flock as she is always the one who decides where they are going to forage and what they are going to do. All the birds seem take their lead from her. Are the flock dynamics still working themselves out? Could I have a potential cockerel on my hands with my BPR? They all still exhibit pullet characteristics. Thanks for any of your own observations or insight. By the way, when my dachshund enters their run or tries to eat from their food, they don't seem to mind her being there - yet...
