She hasn't laid ANYTHING yet, do Easter eggers lay olive sometimes? I thought that I had read somewhere that Ameracaunas can lay pink, but couldn't remember if it was a reliable source. Thanks for the info, I'm going to check the abc Ameracaunas color chart
Yes they do. Along with any other color.
What distinguishes Ameraucanas from EE's is not so much the egg color, it is the fact that Ameraucanas breed true while EE's do not. I have read that Ameraucanas were developed from EE's and white and brown egg layers. So, those egg genes are still out there and can account for the occasional off color egg from an Ameraucana.
However, your girl is an EE. She does not fit the standard description of Ameraucana and will likely not breed true.
