kristip There is a breeder by the name of Wayne Meredith in Mukwanago. That's not all that far from you, maybe 70 minutes or so. He has purebred Ameraucanas, and he sells eggs, chicks, pullets and roosters. He's a great guy, he's been breeding them for 50 years and he helped develop the standard for the breed. He's got some BEAUTIFUL birds. Check the Ameraucana thread for the breeders directory and you'll find his number, or PM me and I'll find it and send it back to you.
I love my ameraucanas. Great birds, gentle and very hardy. By the way, I'm located in southwest Ozaukee County.
