Ameraucana: Can "impurities" be bred out?

[JesWith3]

Through selective breeding, is it at all possible to eventually breed out anything NOT Ameraucana and end up with pure Ameraucanas eventually?
Say for instance Sally breeds her very Ameraucana looking Easter Egger to a true, pure Ameraucana hen and then those babies are bred to a pure Ameraucana and so on....can offspring eventually BE pure somewhere down the line?
I'm sorry if this is a dumb question. I just gotta know! lol

I guess it would be possible, if you kept breeding the offspring to Ameraucanas. I assume each time you bred them, the amount of Easter Egger would half itself. The first time they would be 50% Easter Egger, the second, 25%, and so on. Are you talking about by genetics or by traits?

Short answer, yes absolutely. This is how new varieties of established breeds are created.

"Pure" does not carry the same weight in chickens as it does in, say, dogs. Whether or not a chicken is considered a breed generally depends more on how well they match the standard of perfection than on parentage/pedigree. If her very Ameraucana looking easter egger doesn't have any disqualifying faults, Sally could enter her as an Ameraucana in a poultry show. If she selected offspring with Ameraucana traits those offspring could also be entered as Ameraucana in a show. It would take a lot longer for her to get them up to show winning quality than if she started with birds from a breeder, but eventually she could (in theory) breed show winning Ameraucanas from easter egger stock. That's why the first recommendation is generally to start with the best stock you can afford/find but the second recommendation is if you can't start with the best work with what you've got.
