Has there been any thought or discussion about taking another look at what the AA considers an EE to be? I realize the language came over to the AA with basically everything else but I'm wondering if it might not be worthwhile to revisit the issue.
Here's a specific example that I find it impossible to argue with. Pretty much everybody knows that if you breed two single Mb birds of the same variety together, you are going to get 25% clean-faced. According to the current definition those clean-faced birds would not be considered Ameraucanas.
If I take one of those clean-faced birds and breed it to a double Mb bird of the same variety (or even a different variety in the case of a BBS or WBS), I am going to get 100% single Mb offspring of which any of them could be SQ and potentially even Champion AOSB.
Now imagine the hoopla that would come when someone says, "Well, I bred my best hen to my Easter Egger rooster and got this bird."
But with your example the clean faced offspring aren't Ameraucanas because they don't meet the breed "standard" requiring muffs, regardless of what a breed club or individual thinks. The written Standard is the "last word" for those that are into exhibition.
Since the Standard and judges only deal with phenotype the genotype of parent birds doesn't matter to them, even though it matters to us breeders.
I really don't think any experienced breeder or exhibitor would be surprised by your last statement, understanding that mutts sometimes can and do produce exhibition quality birds. It is just the way it is in the APA/ABA world of exhibition poultry.
I have Easter Eggers (according to the club's definition) right now from different outcrosses that I purposely made to be used to produce Standard Ameraucanas. Those Easter Eggers came from Ameraucanas and some of the F1 chicks from the Easter Eggers will be Ameraucanas.
