Is the last photo in post #8 (BLRWs) a photo of a cockerel? I have a BLRW that I'm still trying to sex . . . 5 m/o, and no spurs, no crowing, no eggs -- nothing to make the job easier. Fudge does look like the bird in your photo, though.
Do you find that this breed takes a very long time to mature sexually?
