The Single Comb White Leghorn is the most popular egg-laying hen, because it reaches maturity early, uses feed efficiently, adapts well to different climates and produces a white-shelled egg, the color preferred by most consumers.
Egg quality is affected by the type feed. For example, shell strength is determined by the amounts of vitamin D, calcium and other minerals in the feed. Yolk color is influenced by pigments in the feed. Natural yellow-orange substances, such as marigold petals, may be added to light-colored feed to enhance color. Artificial colors are not permitted. Hormones are never used in U.S. egg or poultry production.
Eggs sold for humans to eat cannot hatch chicks. They are not fertile. A rooster (male chicken) does not need to be present for a hen to produce an egg. Also, the fresher the egg, the more difficult to remove the shell.
