Just looked at www.ameraucana.org and it states loud and proud that both Ameraucanas and Arauacanas were products of EEs. Boy, was I wrong! I don't know why I didn't look into it for myself before now, but I'm so glad I did.
Aruacanas are the true Breed,
Ameruacanas are now known as a breed
EEs are the cross.
I hate being right.
