That leads me to believe they're not Ameraucana unless you're lucky. Since there are only 8 colors, breeders should keep the colors separated to breed them and keep them true.
I have some Blue Wheaten/Wheatens. Because I know that's the color I have, if I were advertising them or selling them, I would specify their color. I wouldn't just advertise them as "Ameraucanas". But, she could have just assumed you would look at them and see what color they are.
That said, I really only know about the wheatens, and yours seem blue or gray. Maybe in a couple of weeks, once they start feathering out and their legs show better color, you can tell more clearly.
No matter what, they're cute!
