So, Baybrio, in a nutshell, this thread is about APA/ABA poultry. In this culture, breed is defined by shape as put forth by the Standard of Perfection. Although we do recognize that there are some bona fide breeds not yet recognized by the APA/ABA for mere reasons that they have not been popularized sufficiently here and have yet to go through the necessary process for APA/ABA recognition, we also recognize that, along side the emergent culture of neo-chicken-philes, there is also a culture of introducing the "next best thing" that very frequently is naught but a scam. An easy half or more of the newly imported fads (which incidently are only popular among non-APA/ABA folks because you couldn't get one of us to fall for that bologna to save your life) are nothing more than early stage color projects, easily recreated here in one or two season with a little genetic knowledge: the silly "Orpingtons " and "Brahmas" for example. Others are regional landraces brought in from Europe that are more or less the "Barnyard Bantams" of my youth: Swedish Flower Hens, Icelandics, etc... one look at them shows them to be unrefined and genetically unstable--what we would consider certainly unworthy of being called a breed. Whatever these "Legacy" birds are, they're not a breed and they're certainly not old. Either they're the backyard project of a neophyte who's overly enthusiastic about their project, and posting them because of sheer, if under-informed, excitement, OR, in the event that they're trying to sell them and make money off of them, they're a scam, and folks should know that they're being duped.
One of the great advantages to this thread on BYC is that people can come here and get some fairly substantiated and defensible information; so that they don't fall into the trap of the newest fad that leads to nowhere and does nothing to advance poultry or the owners knowledge thereof. In short, if we laugh, it is so that we do not cry.
Edited to add: One of the several advantages to the Standard is that it protects buyers. Using the Standard, a buyer can guage quality of stock and know whether or not he/she is receiving stock of quality or if their receiving junk. Incidentally, the entire hatchery industry is based on selling birds of a certain color as opposed to a certain shape. As a result, very little effort needs to be put into selecting for breed-typical qualities, because they've convinced an uninformed populace that it is "color" that makes the breed. Consequently, they make money with birds of ridiculously poor quality. If folks were more concerned with the "Orpington-ness" of their birds rather than their "Buff-ness" hatcheries would have to step up and produce something worth owning, but because people are content to buy a cheap bird of low breeding with an approximated pattern to run around their garden, the result is a boom of birds of pessimal quality all around the country that do absolutely nothing to preserve or promote real specimens of the breed.
