Some people prefer white shelled eggs. Other people say that brown -shelled eggs are more wholesome to eat.
The truth is that the color of the shell has nothing to do with the food value of the egg. The quality of the egg depends on the variety of factors such as the food eaten by hens.
The coloring of the shell depends on the breed of the hen. Leghorn and Minorca hens lays white -shelled eggs. Most other chickens lay brown-shelled eggs, but the Araucana hens of South America lay blue-shelled eggs.
