This is EXACTLY how poultry breeding and showing works. You could splice together the genes from an Ameracauna, a Polish bird, and your neighbor's doberman, and if the resulting genetic mess meets the specification for a Delaware - IT IS A DELAWARE. It can be shown as a Delaware.
Parentage DOES NOT MATTER. The word "PURE" means nothing.
This is how poultry judging and classification works. PHENOTYPE is not just everything, it is THE ONLY THING THAT MATTERS.
What you are condoning is against all showing and breeding guidelines, rules and ethics... yes, a bird with the correct phenotype could win in a show when it is not an actual correct breed... in fact, someone once did it... and was then banned and blacklisted... thus the requirements that breeds must breed true at least 50% of the time... and the time and energy it takes to make a mixed bird correct in phenotype to not only show, but win for a breed it is not, is considerably more than it would take to simply breed the proper breed and show it...
Without the proper genotype they will not breed true and meet standard requirements and that is what is meant when a breed of poultry is called 'purebred'... most of our modern day breeds are amalgams of different breeds bred together until they breed true to the type desired... crossing in one of the original base breeds to improve a flaw and rebreed back to the existing breed is a common practice among breeders... only once the breed returns to breeding true is it accepted by that breeder as being pure again...
And to the OP, @Chickyloubou I give you my sincere apology that your desire to learn and gain knowledge has devolved into such an unnecessary spiraling debate... unfortunately with any of these breeds and the term Easter Egger, you will find this happens often... several people gave you some good advice and a starting base for learning... I hope this experience does not reflect too badly on your desire to know more...
Oh, and I do raise and breed Araucanas, Ameraucanas and Cream Legbars... contrary to popular belief, Araucanas are not a 'rumpless, tufted, blue egg laying bird' from South America... it was created using 2 main base breeds found in South America, one was rumpless and tufted and one was tailed and layed blue eggs... just as smooth faced happens in Araucanas, so do tails come out to haunt us... all we can do is keep breeding forward and improve as best we can...
