Best Answer The color of eggs comes exclusively from the pigment in the outer layer of the shell and may range from an almost pure white to a deep brown, with many shades in between. The only determinant of egg color is the breed of the chicken. Because white eggs are preferred in almost every region of the country, the Single-Comb White Leghorn has become by far the favorite egg-layer in the United States.
The Leghorn is prized for many reasons: it reaches maturity earlier than most pullets; it uhlizes its feed efficiently; it is relatively small (an important consideration when most chickens are kept in cages even smaller than New York City studio apartments); it is hardy, adapting well to different climates; and most important, it produces a large number of eggs. If more consumers went along with New England's preference for brown eggs, more breeds such as the Rhode Island Red, New Hampshire, and Plymouth Rock would be provided to produce them.
Egg yolks also range dramatically in color, but yolk variations are caused by dietary differences rather than genetic ones. Yolk color is influenced primarily by the pigments in the chicken feed. If the hen gets plenty of yellow-orange plant pigments known as xanthophylls, the pigments will be deposited in the yolk. Hens receiving mash with yellow corn and alfalfa meal will lay eggs with medium yellow yolks. Those fed on wheat or barley produce lighter yolks. A totally colorless diet, such as white corn, will yield a colorless yolk. For cosmetic reasons alone, farmers avoid giving chickens a colorless diet, because consumers prefer a yellowish hue to their yolks.
A farmer raises chickens for eggs and meat. Any chicken that does not lay at least one egg a week is moved to?
A farmer raises chickens for eggs and meat. Any chicken that does not lay at least one egg a week is moved to the slaughterhouse. The farmer has 765 chickens that can lay one egg each day. Each day 80% of the chickens lay eggs. How many eggs does the farmer collect each day?
