Probably EE's but several questions. Did they spell it AmerAUcana or AmerIcana? The first should be the breed while the second are EE's. Which hatchery did they come from? Several hatcheries do now carry true Ameraucanas while the others have only EE's labeled Americanas. How much did you pay for them? If they are true Ameraucanas they should have been priced higher than the EE's.
That said, I have and have had both Ameraucanas and EE's and I absolutely love my EE's. They lay some of the most beautiful blue eggs I have gotten and they lay a goodly number.
And when I do breed and hatch my own, I breed for egg color and number.
