Easter Egger

Bird

An Easter Egger is any chicken that possesses the "blue egg" gene, but doesn't fully meet any breed description as defined in the American Poultry Association (APA) and/or the American Bantam Association (ABA) standards. The name derives from the resemblance of their colorful eggs to Easter eggs. Araucana, Ameraucana, and Easter Eggers are descended from the same founder stock that spread around the world from Chile and the Falklands.
