Are brown eggs better than white eggs? Tradition says that brown eggs are more nutritive than white eggs, and hence, it is not surprising that they are more expensive in most of the places where they are sold. However, this is not true: from the aspect of taste and nutrition, a brown egg is identical to a white egg. The colour of an egg is defined by the bree of the chicken. According to a mexican poultry, a white feather hen will lay white eggs, while red-brown chickens will provide brown eggs. Regarding to the colour of the yolk, this is determined by the corn quality used to feed the chicken, but it does not define the colour of the eggshell. So why are brown eggs more expensive? There are two explanations: first, brown chickens are bigger than white chickens, therefore, they eat more corn and hence, their eggs are more expensive. Second, due to the popular belief that brown eggs are better, they are in high demand that implies high prices.
