Beautiful taxidermy Onagadorie rooster Onagadori (Japanese: 尾 長 鶏) is a breed of chicken from Kochi prefecture in Japan that often loses tail and saddle feathers due to the presence of the Gt gene. Onagadoris in Japan Onagadoris have been known since the Edo era, when farmers in the village of Osasa (in today's Kochi prefecture) started breeding cocks with extremely long tails. Although the breed was declared a national cultural property in 1923 [1], the number of animals fell to nine. After the Second World War the breed continued to be bred, where it was forbidden to export animals or eggs. Characteristics The most striking feature of the onagadori is the extremely long tail, due to the action of the autosomal dominant Gt gene and to a lesser extent the recessive mt gene. Homozygous animals with the Gt gene have the maximum tail growth. 2] The breed occurs in partridge, silver partridge, yellow partridge and white. It has the shape of a grouse and is relatively light in weight (the cocks up to 1.8 kg). Breeding outside Japan Before 1900, onagadoris were introduced in Europe and, despite the export ban, again from the 1970s onwards. Several tribes originally came from the Netherlands, Germany and the United States. Because many strains suffered from a genetic weakness, crossbreeding took place with other breeds, such as Totenko's, white bucks and especially the German Phoenix them.
