Any chance this BO on the right is still a hen?? I pretty sure I already know the answer, but still holding out hope! Tail feathers look the same as the other hopeful hens. The only major difference in appearance is obviously the comb and waddles. I do have 2 other roosters that are the same age and they've started crowing, but I haven't heard this one attempt. Both chicks in this picture were hatched March 22.
