Brown eggs are packaged to make consumers think of open fields and free-roaming hens, when in fact the chickens producing them are kept in the same cramped, sunless coops, and fed the same formulated diet as their white-laying counterparts. The color of an egg is determined by the hen's genetics.
Free-range eggs contain up to a third less cholesterol than conventional supermarket eggs. A standard egg contains an average of 423 milligrams of cholesterol, while free-range eggs contain an average of 277 milligrams. If cholesterol is a concern for you, free-range eggs are a smart choice.
