I did a search and found a good thread about this but still have a few questions. I am buying some eggs from a guy close to me. He has Ameraucana chickens (to keep this simple we will asume they really are and not EE's) and RIR hens. His rooster is an Ameraucana cross with a black Australorp. So this is what I am asuming will happen with the egg color (please correct me if I am wrong) : The Amer. hens crossed with the rooster will most likely create chicks that lay around 75% blue eggs and 25% green eggs (with maybe a few brown eggs in between?). And the RIR hens crossed with the rooster will create hens that lay 50% brown, 25% green and 25% blue? I now there are a lot of variables in this so I'm not even sure if it can be figured out. But I know there are some people on here that really know there genetics so I'm sure someone can set me straight.
