No. Well, chickhatchery.com does, but, I don't know if you call him a hatchery or not. He's a breeder who sells day old chicks of every recognized and un-recognized color of true Ameraucana.
I've heard good things about Meyer Hatchery, but, like just about every hatchery out there, they don't sell true Ameracaunas. Otherwise, they would not use "EE" and "Ameracauna" interchangeably on their website or in their catalog. True Ameracauna breeders know the distinction and will clarify it--sometimes a little arrogantly
But, if you just want something that looks like an Ameracauna, than Meyer is a good place to buy from.
