Pictured below is one of our layers. We were told when we bought her that she was a barred rock. There is something else in her, though, as she lays green eggs (front-center egg in the other picture). Can anybody tell me what it might be? She lays the richest, tastiest eggs I have ever had in my life. They are way better than the other hens and genetics is the only variable. We have been trying to get her eggs to hatch and were successful in breeding her to our only rooster (a barnevelder). I'm hoping the eggs are just as good.
I'm guessing you have a barn yard mutt of the breed Ameraucana (crossed with a barred rock) Easter Egger is another common term for green/blue egg layers. I have a few and I like them. My oldest is 6 years old and laid 2/3's of the days during peak laying season.
