Introduction to Blues
By Graham Miller
Champion Breeder and Exhibitor
As attractive as the white mutation of Gloster is, it infrequently takes second
place to the dominant blue. The clear white we can compare with the clear
normal, while the blue is the counterpart of the green self.
The blue Gloster that exhibits excellent form, coupled with fine dark penciling on
a blue ground, particularly if it is a corona possessing that dark vein on every
crest feather which accentuates its radiation, never fails in its attraction. It is
advisable to breed for totally self birds that show no lightness, especially in the
throat.
The blue Gloster is only a pigmented white and is, therefore, subject to the same
laws of inheritance, always being paired with normal breeding partners.
Pairings to produce dominant blues are:
1. Dominant blue cock x green hen. Result: Dominant blue young, green young.
2. Green cock x blue hen. Result: As previous mating.
3. Dominant blue cock x cinnamon hen. Result: Dominant blue cocks carrying
cinnamon. Dominant blue hens and green hens.
4. Cinnamon cock x dominant blue hen. Result: Dominant blue cocks carrying
cinnamon. Green cocks carrying cinnamon. Dominant fawn hens. Cinnamon hens.
5. Dominant blue cock cinnamon carrier x cinnamon hen. Result: Dominant blue
cocks carrying cinnamon. Green cocks carrying cinnamon. Dominant fawn
cocks. Cinnamon cocks. Dominant blue hens. Green hens. Dominant fawn hens.
