Is there a difference in nutritional value between brown-shelled eggs and white-shelled eggs?
There is no difference either in nutritional value or flavor between brown-shelled and white-shelled eggs. The color of the eggshell is determined by the breed of hen. Most chicken eggs are white or brown. Brown eggs come in a variety of shades from light to dark. The Single Comb White Leghorn, which lays white eggs, is the dominant breed of hen in the United States. In New England, where brown eggs bring a premium price, Rhode Island Reds, New Hampshires, and Plymouth Rocks are popular breeds of hen that lay brown eggs.
