I only have Araucanas. With all the confusion about EE or Americaunas, I can see how people are mislead and confused. I was at a swap last weekend where there were Olive Eggers, whatever that is. To be honest with you, I am kind of one track when it comes to the differences, I only know the araucanas and adopt a kind of "uh huh, I [really don't] see" confused look on my face when people start talking about the others. As to the seller's comment from Craigslist, I for one can attest to the fact that the araucanas are no less fertile than any other of my breeds. Probably more so to be honest. If I can bet anything is going to hatch from my bator, it will be an araucana from a blue-green egg.
