Penedesenca

Bird

Penedesenca is a breed of chicken originating in the Spanish province of Catalonia, in the area around Vilafranca del Penedès, which is the main town in the region known as "Penedès". It was developed in the first half of the 20th century from native barnyard chickens, and today is noted for producing copious amounts of very dark brown eggs, said to be among the darkest of any breed of chicken.
