I have NO idea what they are because they are almost a year old and they have not given us any eggs OR crowing. The only thing I know about them is their position(s) in their little group. Molly (the white) is the Alpha, although Lulu (The black) often tries to over take. Lulu was sick and weak and very small when I had her and did not grow for a while so I am surprised that she's so spunky. Molly (white) is the alert role, too -- and often alerts to danger. But if they ARE hens.. why the lack of eggs? Anyone have a 10-11 month old that haven't layed eggs, yet? Or a flock that hasn't? But as to their true genders? I have no idea. Unfortunately Lulu (the black) is hard to see in these pictures. I will have to come back to her another time this weekend.
