I thought that a true EE came from a Hen or Rooster Ameraucana mixed with another breed.
Ugh! I quoted the wrong one. Sorry.
That is my understanding Vallychicks. An EE has the thick neck like an Ameraucana, the green legs (commonly), and the pea comb. An Ameraucana + other breed = EE be it a blue egger, olive, pink, what not.
I am not sure what Cream Legbars mixed with other breeds would be called, the color combos do make sense though!
