There are only white or brown eggs
Chicken eggs can be different, but we usually only see brown and white ones. The color of the shell depends on the breed: leghorn chickens have white eggs and Rhode Island chickens have brown eggs. Some breeds (like the Araucana, Ameraucana, and others) have blue or green eggs. The color depends on the pigment: protoporphyrin makes the shell brown and biliverdin makes it blue and green. The chickens’ diet also matters: if a hen doesn’t get enough amino acids, the shell will be dull. But it doesn’t affect the quality of the egg.
