The following picture shows that the inside of a brown egg shell is white.
The shells of Araucana and Ameraucana chickens, however, are pale blue on both the outside and inside. There are hybrid varieties of chickens that have been crossed with one of these breeds and carry the blue egg gene. Their eggs can be pale blue or pale green, or sometimes even cream or pink colored. They are called Easter Eggers, but they are not a standard breed. When an Araucana or Ameraucana is crossed with a dark brown egg layer (such as a Marans or Welsummer, for example), the brown pigment layer on the blue shell produces an olive green colored egg. These mixed breeds are called Olive Eggers.
Eggs are generally of the same essence on the inside. The color of the egg shell does not effect the appearance, the taste, or the nutritional value of the egg itself. Those qualities are effected by the diet, health and environment of the chicken. Hens that have access to the outdoors and are able to forage for their food lay eggs that have enhanced flavor and nutritional value. According to the USDA, compared to commercially raised chickens, the eggs of free-range chickens have:
1/3 less cholesterol
1/4 less saturated fat
2/3 more vitamin A
2 times more omega-3 fatty acids
3 times more vitamin E
7 times more beta carotene
The variety of colors of chickens' eggs is surprising and beautiful. If you have a flock of these various producers, you sure don't need to dye Easter eggs!
