I just want to add, don't be discouraged if they are EE's. I found out the same thing with my Ameracauna's to EE. They have become my favorite chickens, sitting on our laps and letting me love on them. I wouldn't give them back for the real ones.
Thank you for this wonderful information. It is a little sad for new comers. I went to a local feed store wanting Ameraucana chicks thinking that is what I would get. Now I'm sure they will be EE and that's OK but they should not sell them as something they are not. Mine are only 3 weeks old...
