Well it used to stand with it's chest out and peck at the dog and bunny, but I don't know if it does that anymore. It will stand upright sometimes, and squat other times.If I were to see this without an age, I would say girl. But 9 weeks is pretty young and that comb is a bit larger than my girls' were. I would give it a few more weeks. A boy should become more obvious then. How does it behave?
