Easter Eggers lay olive green/blueish/pinkish eggs. They are sometimes a cross of an Americana roo on any other breed hen or a cross of other EEs. I blieve pure Americanas lay blue eggs.
My EEs have just started laying and if you would be interested in some olive green hatching eggs, I will put you on my list and contact you after I test fertility and start selling. They will be $10.00 a dozen plus shipping to your zip code. It will probably be another month before I start selling.
