I had wanted to include trhe Buckeye along with several other indigenous breeds. But for the sake of keeping the list short , I left them off.
Also I am a little biased in that I define a heritage chicken to be one that could represent poultry's "Small Folck Golden Age," roughyl 1900-1940. The Buckey fits teh timeline perfectly, being first created in the late 19th Century, but it wasn't wide spread during the heritage period. Well, not like the others I've mentioned.
Buckeye Facts
The Buckeye is a breed of chicken originating in the U.S. state of Ohio. Created in the late 19th century, Buckeyes are the only breed of American chicken known to have been created by a woman, and the only one to have a small "pea" comb. As of 2008, Buckeyes are extremely rare, and breed conservation organizations have recognized them as critically endangered. The breed's name is derived from Ohio's nickname of "Buckeye state", and their color is said ideally to resemble the seeds of the Ohio Buckeye plant (Aesculus glabra). They are largely utilitarian birds: lacking fanciful colors, instead they have a decent laying ability and strong meat production characteristics. Buckeyes are yellow skinned chickens who lay brown eggs.
The Buckeye was first bred and developed in 1896, by a Warren, Ohio resident named Nettie Metcalf. They are the only American breed of chicken known to have been developed by a woman, despite the fact that women were customarily given charge of the household poultry flock throughout much of U.S. history. Metcalf crossbred Barred Plymouth Rocks, Buff Cochins, Rhode Island Reds, and some blackbreasted red games to produce the Buckeye. Her goal was a functional breed that could produce well in the bitter Midwest winters.
The Buckeye was admitted to the American Poultry Association's Standard of Perfection in 1904. Entrance in to the Standard of Perfection signifies official certification as a breed by the Association, and thus allows Buckeyes to be entered in to poultry shows and judged according to the breed standard (as outlined in the Standard of Perfection). The recognition of Buckeyes in the Standard has been a significant factor in its survival.
However, largely due its lack of color variations, the Buckeye has never been an especially popular exhibition breed. Not adopted by commercial operations, the Buckeye has generally been a bird of smaller farm flocks. Today, it is listed as critically endangered by the American Livestock Breeds Conservancy, as there are estimated to be five or fewer flocks, with no more than 500 breeding birds. The breed is also included in the Slow Food USA Ark of Taste, a catalog of heritage foods in danger of extinction.
The Buckeye male weighs an average of 9 lbs (4.1 kg), and the hen 6.5 lbs (3 kg). The breed has yellow skin and lays brown eggs. Its primary color is a mahogany red with black tails; sometimes males have other dark feathering. According to the breed standard, a Buckeye's plumage should ideally resemble the hue of an Ohio Buckeye's seeds.
The Buckeye is the only purely American breed to sport a pea comb, and this, combined with its stocky build, makes it a supremely cold hardy chicken. Other breeds of fowl developed in the U.S. (such as the Ameraucana) may sport pea combs, but these chickens were primarily created from foreign birds. It also bears some traits of Game fowl in frame and disposition, being assertive in character and a very good forager. Generally calm, the cock may become aggressive. Despite its game heritage, it tolerates confinement well, and is said by breeders to be disinclined towards feather picking. A good meat producer and layer of a fair number of eggs, the Buckeye is a dual purpose chicken wellsuited to small farmyard and backyard flocks.
It is not the only only American breed to have a pea comb, though -to admit that, you would have to eliminate the Wyandotte!
Depending on hoew you defien heritage this one would be a dandy. You would get a great homespun bird - and help an endangered breed, too.
