When should you know if a buff brahma is a roo or hen? I have a buff brahma that, when I posted it at 6 weeks was identified as a hen. Her comb is just starting to turn a light pink and she/he is between 8 and 9 weeks. The only reason we are still questioning the sweet thing is her voice. She is always crowing like a hawk. It does not sound like a hen or roo to me. It is a CAAAAA, Caaaa sound. She does it when she is alone or wants back in her home. What do you all think? I took some pics to help with the gender game.
