http://www.irelandoldnews.com/Cork/1856/MAY.html ~ EXTRAORDINARY FOWL.—A chicken of the Cochin China species was left at our Office to-day, by a gentleman residing in this city, which exhibits a singular freak of nature. The bird is fully formed, but, where the tail ought to be looked for, a rather imperfectly formed leg, with three claws fully developed, protrudes, thus supplying it with a leg more than the usual complement. The little animal lived for two or three days, but the mal-formation referred to was not observed until after its death.
