I would be happy if it stays a pullet. It is a confusing chick, male feathering pattern, female comb color and size. I can't tell if the hackle feathers are pointed or if it is just the coloring making them look that way. If she is a pullet, she is definetly the dominate one. Very bossy to the others and the first at everything.
I'm no expert on that breed, however I have just raised 7 chicks and the ones with the most outgoing, bossy personalities all turned out to be boys. The girls were quiet in comparison.
