The DSM Yolk Color Fan is a 16-scale color index that distinguishes yolk color and is widely used in the poultry industry. Under the scale, each number corresponds with a different shade.
The color of an egg yolk is entirely dependent upon a hen's diet, an expert said. A diet with more carotenes and xanthophylls will produce a darker yolk.
The domestic turkey (Meleagris gallopavo domesticus) is a large fowl, one of the two species in the genus Meleagris and the same species as the wild turkey.Although turkey domestication was thought to have occurred in central Mesoamerica at least 2,000 years ago, [1] recent research suggests a possible second domestication event in the area that is now the southwestern United States between ...

[1] [2] [5] It was developed from 1934 at the Beltsville Agricultural Research Center of the United States Department of Agriculture in Beltsville, Maryland, [6] and was named for that town and for its physical characteristics — small size and white plumage.

Naked Neck chickens. Despite its highly unusual appearance, the breed is not particularly known as an exhibition bird, and is a dual-purpose utility chicken. They lay a respectable number of light brown eggs, and are considered desirable for meat production because they need less plucking and they have a meaty body.
A bewildering array of colors and patterns can now be found in the domestic fowl. [1] In the last decades white plumage color has become essential for the efficient processing of broilers and most types of meat-type poultry. Slaughterhouses and meat processing plants require poultry with a white or very light undercolor to produce carcasses ...

Egg white consists primarily of about 90% water into which about 10% proteins (including albumins, mucoproteins, and globulins) are dissolved. Unlike the yolk, which is high in lipids (fats), egg white contains almost no fat, and carbohydrate content is less than 1%. Egg whites contain about 56% of the protein in the egg.
