Yellow Bill

Back to previous page 

HISTORY:   It is not known by whom or when the first Yellow Billed was bred. It has been suggested that the first bird appeared in the wild or that selective breeding for the paler bill was responsible for its occurrence.


  •  Yellow Bill x Yellow Bill = Yellow Bill cocks and hens
  •  Yellow Bill x Grey = Grey/YB cocks and hens *
  •  Grey/Yellow Bill x Yellow Bill =Yellow Bill & Grey/Yellow Bill  cocks and hens *
  •  Grey/Yellow Bill x Grey = Grey & Grey/Yellow Bill cocks and hens **
  •  Grey/Yellow Bill x Grey/Yellow Bill = Grey, Yellow Bill  & Grey/Yellow Bill cocks and hens **

 *  The reverse matings will give the same results.

** This mating is not recommended as it is visually impossible to detect which Greys are pure.
