FYI,
Birds must breed true at least 50% of the time. This is standard for all colors in the APA and ABA, which lets the blue variety of any breed exist.
Egg color is mentioned only as a charateristic in the Standard as "blue egg coloration". My buffs lay a poor colored egg, yet they are still ameraucanas. This is one of the youngest breeds in the Standard. The marans are new to America, but they have been around a long time.
I for one, do consider a mixed colored ameraucana an ameraucana; but only if I know who the breeder is and why. I know to tell people what they are and generally my birds like this are project birds. I believe the problem with the mixed colors thing is that the Club doesn't want new people to the breed to start mixing colors on a regular basis and get a whole flock of willy nilly colored birds. You have therefore missed the point of the purebred bird. Orpingtons aren't generally sold as mixed colors, neither are wyandottes or leghorns. It tends to help keep the easter egger confusion to a minimum.
Other breeds don't have to deal with the easter egger problem; a mixed bird is a mixed bird. Thank you Mr. Hatchery Man.......
