What foundational chicken stock is the Yokohama directly descended from on Kyushu island?
Answer
*Onagadori* chicken
The historical development of the Yokohama chicken traces back to the island of Kyushu in Japan, where the foundational stock originated. This stock was the native *Onagadori* chicken. The *Onagadori* breed is genetically significant because its lineage possesses the trait that prevents the main tail feathers from undergoing their typical annual molt, thereby allowing these feathers to achieve extreme lengths over time. This essential genetic component for long tail growth was carried forward into the birds that would eventually become the Yokohama and the related Phoenix breeds when they were later introduced and developed further outside of Japan.
