Thanks everyone for your input. Farah is very pretty and she's one of the most adventurous of all 25 in the order (various breeds). At least I'll get more green eggs! Only one other of the Ameracanas that I ordered (out of 4) turned out to be a pullet, so this is an OK outcome.
Do you think McMurray hatchery would have included an EE (Americana/Arauncana) as the 26th "rare exotic" chick. We thought "Farah" was possibly a phoenix or a golden penciled hamburg. But I can no longer deny she looks looks just like some of the other EEs that have been posted on this site...
