Best examples are from the club web sites. Also the best reliable source for information on the breed will be there as well. They are Ameraucana Alliance and Ameraucana Breeders club. They both have listing of breeders that are apart of the clubs.
There have been alot of EEs that have been sold as Ameraucana resently. Mostly of the blue and lavender varieties. I also think people buying don't read all the info on add. I had a guy come buy 3 EE pullets from me and asked if they where Ameraucana.
My add stated the crosses that made the EE...
The breeders I've seen or messaged via email consider them pet quality.
I would say EE*Ameraucana but that might only matter to the person that has them. I'm also not in either clube to propose anything of the sort.
They should not be laying brown. There is a guide card from the clubs for the different shades of blue.
On new colors being developed, if it has a cross in from another breed you could get green. If it's early in the project you could get brown but if it's finished it should only be blue.
Also if you want different colors and to be able to keep and breed them together I would go blue or blue wheaten. You get in the case of blue: blue, black and splash. For blue wheaten you get blue wheaten, wheaten, splash wheaten.
That would be a correct assumption. The color wouldn't be recognized but the bird itself is still an Ameraucana. I think they show as Ameraucana but in all other. That is how they work towards getting new colors recognized. There's alot more work to it than just mixing them to get new colors...
