Any Ameraucanas or Araucanas that are being advertized as laying any colored eggs other than blue are Easter Eggers as pure Ameraucanas and Araucanas lay only blue eggs. Easter Eggers are hybrids produced by crossing blue egg laying breeds such as Ameraucanas or Araucanas with brown egg laying breeds to produce offspring that lay eggs in colors other than just blue. There is a good article at http://www.the-chicken-chick.com/2011/09/ameraucana-easter-egger-or-araucana.html explaining the differences between Ameraucanas, Araucanas, and Easter Eggers. Our Easer Eggers are my granddaughter's (pictured in my avatar) favorite hens. She loves their different colored eggs. )
