You can still run into greens with them. They are called EEs unless they are an acceptable type according to the APA--like Wheaten Ameraucana.
Green indicates that there is some brown in the genes.
I hope I explained that correctly. Egg color does not indicate weather a Hen is an Ameraucana or an EE. It is the type and breeder that counts. Ideally they would lay pretty blue eggs though.
