Where did you get them? I don't believe he's one of the recognised colours of Ameraucana, but I'm hardly an expert. He could very possibly be someone's colour breeding project.Interesting, thanks! I almost gave him away today before I realized how special he is. The AC's are still not cheap though. Greenfire Farms lists them for $400 and they are out of stock.
The female version of the Ameraucana that I have from the same batch lay the beautiful blue eggs. In the past I have had what I thought were Easter Eggers that layed more of a green colored egg.
And EEs can lay blue eggs. It's rare, but it does happen.
