Tibetan/tuxedos sexed by beak color

[rachel]

I just wanted to update that the theory in Monarc's info page about tibetan roos having black beaks with the hens having the dark brown ones seems to be true with my birds (worked for the tuxedos too). Does anyone have an example of a tibetan that this is NOT true for?
Maybe then we would just have to work on getting some A&M sexlink trait going....
