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.
Chicks of black plumage varieties are also black, with some black in beaks, legs and dorsal side of the toes, but with a varying degree of white or grayish white in the ventral surface and the tip of the wings. [1] To the naked eye, the length of the down in black chicks is also shorter than that of any other color variety.
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.
Breeders and fanciers of chickens accurately describe the colours and patterns [1] of the feathers of chicken breeds and varieties. This is a list of the terms used in this context. This is a list of the terms used in this context.
Chicks down color of solid white chicken breeds can vary from a light creamy white, through different yellow shades, to a toasted orange. [2] In adult phase, the entire surface of the plumage is pure white due to the absence of melanin pigmentation in all parts of the feathers.
Plumage (from Latin pluma 'feather') is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes.
