Castellana Negra
The or is a Spanish breed of domestic chicken. It is a good egg-laying breed, rustic and disease-resistant. It was formerly widely kept and commercially exploited in Spain. Since the invasion of commercial hybrid layer chickens and the spread of highly intensive chicken farming methods it has almost disappeared.〔
==History==
The Castellana Negra is thought to have been introduced to Al-Andalus by the Moorish invaders, and for this reason was sometimes known as ''moruna'', "Moorish". It was widespread in southern and central Spain, but was not known in the northern part of the Iberian Peninsula until the late nineteenth century. Black chickens were known in various parts of the country under regional names such as the Zamorana in the province of Zamora, the Leonesa in the province of León (both in the autonomous community of Castilla y León), the Andaluza Negra in Andalucia or the Jerezana in the area of Jerez de la Frontera. How the black chickens of Castilla y León were selected and unified to become a breed is not documented. From the late nineteenth century it was so considered, and a breed standard was drawn up in 1926 by D. Enrique P. de Villamil;〔 this was approved in 1930.〔 Following the introduction of battery farming and imported commercial egg-laying hybrids, the Castellana Negra came close to disappearing. It was included in the conservation programme for indigenous chicken breeds of the Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, a public agrarian research institute, from 1975 to 2010.〔
Initial steps towards recovery of the breed were reported in 1981. Breeding was begun with two birds identified in Córdoba, and a further ten from Mérida in Extremadura. The total population in Spain at that time was believed to be 150–200 birds.〔 In 2009 there were some hundreds of Castellana Negra birds kept by the Instituto Nacional de Investigación Agraria, and about a thousand at the agricultural institute of the University of Valladolid at Soria. Isolated nuclei of the breed, not all pure-bred, were also reported from Zamora, León and Salamanca in Castilla y León, from the area of Toledo in Castilla-La Mancha, and from Andalucia.〔
The Castellana Negra was not included in the official list of indigenous Spanish breeds in the royal decree of 26 December 2008, which established the national livestock breed conservation programme,〔 but was added to it by a ministerial order dated 4 March 2010.〔 A new breed standard was approved on 24 March 2010 in a resolution which also authorised the breeders' association, the Asociación Nacional de Criadores de Gallinas Selectas de Pura Raza Castellana, to maintain the flock book for the breed.〔 The Castellana Negra is listed among the indigenous breeds at risk of extinction.〔
