Introduction: The Mystery of Blue Eggs
Eggs come in various colors, ranging from pure white to shades of brown. However, blue eggs are a mystery to many people. They are not commonly found in grocery stores, and some people have never even seen one. This leads to the question: who makes blue eggs?
The Genetics of Egg Colors
To understand who makes blue eggs, it is important to understand the genetics of egg colors. The color of an egg is determined by the genes passed down from the hen’s parents. The genes responsible for eggshell color are located on the same chromosome as the genes for feather color. This means that the color of a hen’s feathers can give an indication of the color of her eggs.
The Role of Oocyanin in Blue Eggs
The blue color of eggs is caused by a pigment called oocyanin, which is deposited on the surface of the eggshell during formation. Oocyanin is produced in the oviduct of the hen and is responsible for the blue-green color of some eggs. The intensity of the color depends on the amount of oocyanin deposited on the eggshell.
The Origin of Blue Egg-Laying Breeds
Blue egg-laying breeds originated in South America, particularly in Chile and Peru. The Araucana chicken was the first breed to be recognized for its blue eggs in the 1930s. These chickens were brought to the United States in the 1960s. Since then, other breeds that lay blue eggs have been developed through breeding programs.
