Hi there! I would recommend checking out the Breeders Directory on Ameraucana.org.
http://www.ameraucana.org/BreedersDirectory.htm
They have breeders listed by state with their contact information. In fact, here are the breeders listed for Arizona. (The numbers and letters beside each listing represent the colors and whether they sell eggs or chicks, started birds, etc.)
