For Blue Andalusians, check out The Farmer's Wife [a BYCer] at her website:
http://www.gabbardhatchingeggs.com/shop.html
I got my Blue Andalusians from her and got a great hatch, really healthy chicks and they grew in to very nice birds.
She also sells on
eBay as julie3810. I've bought 4 sets of eggs from her over the last year and they were all excellent.
For real Ameraucanas, you can buy from grandmacrazycraft on
eBay - I've gotten two sets of eggs from her in the last year and both sets yielded excellent quality "true" Ameraucanas - mostly beautiful blues if you like that color. [ I do LOL!]. I have bought from 6 other "Ameraucana" sellers who *claimed* to have the "real deal" and I have about 50 mutts from their eggs running around my yard now. LOL! [cute chickens, but mutts for sure!].
Pips and Peeps [also a BYCer]
http://home.sprynet.com/~rribbeck/ has a fantastic reputation for excellent Ameraucanas. I have not personally bought from her [yet
], but I hear enough great things about her birds that I wouldn't hesitate to buy from her.
In addition, pasofinofarm has posted Ameraucana eggs for sale here on BYC
https://www.backyardchickens.com/forum/viewtopic.php?id=121820 and her photos of her birds show excellent quality Ameraucanas too - I want to buy from her as well, but haven't yet.
Anyway, hope that helps.
