A hen displaying the "dominant white" plumage color genotype. In poultry standards, solid white is coloration of plumage in chickens (Gallus gallus domesticus) characterized by a uniform pure white color across all feathers, which is not generally associated with depigmentation in any other part of the body.

Solid black plumage color refers to a plumage pattern in chickens (Gallus gallus domesticus) characterized by a uniform, black color across all feathers. There are chicken breeds where the typical plumage color is black, such as Australorp , Sumatra , White-Faced Black Spanish , Jersey Giant and others.
Chickens of both sexes develop male-type plumage after gonadectomization. Strictly speaking, they develop a neutral plumage with long acute feathers, like those of male plumage, because ovarian hormone is also necessary to develop female plumage. [6] It is well known that some of the main estrogens derive from androgens.
Figure 1. Feathering types in ten-day-old chicks.Left: Fast normal-feathering chick. Right: Delayed-feathering chick carrying sex-linked K gene. Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.

The physical traits used to distinguish chicken breeds are size, plumage color, comb type, skin color, number of toes, amount of feathering, egg color, and place of origin. [1] They are also roughly divided by primary use, whether for eggs, meat, or ornamental purposes, and with some considered to be dual-purpose.
The "lavender" gene (lav) in the chicken causes the dilution of both black (eumelanin) and red/brown (phaeomelanin) pigments, so according to color background, dilution due to "lavender" gives a sort of plumage color patterns: On an extended black background, this condition causes the entire surface of the body an even shade of light slaty blue, which is the typical phenotype known as '"self ...
