Which breeds of chicken are known to lay green or blue eggs?

The breeds known for laying green or blue eggs are Araucana, Ameraucana, and Easter Eggers. Each of these breeds has genetic traits that allow them to produce eggs in colors ranging from light blue to olive green.

Araucanas are originally from South America and are recognized for their unique tufted ears and ability to lay blue eggs. Ameraucanas are derived from Araucanas and have been developed in the U.S., also consistently producing blue eggs, often prized for their unique color and for being friendly and hardy. Easter Eggers are not a true breed but are hybrids that often carry the blue egg gene, resulting in a variety of egg colors, including green.

In contrast, the other breeds listed do not produce blue or green eggs. Rhode Island Reds and Leghorns primarily lay brown eggs, while Plymouth Rocks and Sussex are known for brown and cream-colored eggs, respectively. Wyandottes and Orpingtons typically also produce brown eggs. This distinction is important for those interested in the variety of egg production based on chicken breeds.
