My Pet Chicken (www.mypetchicken.com) also sells both true Ameraucana and Easter eggers but if I remember correctly without looking it up, the true Ameraucanas are 20.00 per day old pullet while the EE's are three something (plus shipping.) Last year they offered only two colors.
I do believe the My Pet Chicken gets their Ameraucanas from Meyers as they get other breeds from them.
You're correct. My Pet Chicken doesn't actually breed their Ameraucanas but gets them from Meyer Hatchery which is why I said that Meyer is the only hatchery that actually "breeds" and sells them.
