![]() ![]() The Penedesenca and Empordanesca produce extremely dark brown eggs, but their earlobes are white. Ameraucanas and Araucanas both have red earlobes yet lay blue eggs. If you are familiar with Redcap, Crevecoeur, and Dorking breeds, you may know that they lay white eggs despite having red earlobes. Now, there are some exceptions to the theory. Meanwhile, hens with red earlobes tend to lay brown eggs. Many hens that have white earlobes lay white-shelled eggs. It is not completely accurate, but there is some sense to it. Some breeders will use the color of a hen’s earlobes to determine what the eggshell color will be. They don’t want their chickens who lay brown eggs all the time to suddenly start laying blue ones in a few generations. This is why breeders tend to be picky when selecting which chickens they want to use for solidifying a breed’s standard. ![]() The color of a chicken and their eggs is based purely on genetics.

Here are some ways you get different green eggshells: Green is the result of the brown pigment overlaying the blue shell. Green Eggsīiliverdin is also responsible for greenish tints, but only when a blue-egg breed is crossed with a brown egg-laying breed. It is believed that blue shells became dominant when a harmless endogenous avian retrovirus found its way into the DNA of chickens. Where brown pigment colors the surface of the egg, blue pigment mixes more easily with the calcium carbonate, so the bluish tint is throughout the entire shell.īlue eggs are a dominant trait. But where does the blue pigment come from? Turns out, it is from biliverdin, a pigment that results from bile. Stunning blue eggs are always a delightful surprise in the egg basket. ![]()
