波利斯褐鸡

A commercial hybrid laying hen, not covered by CITES, the species conservation law or the cultural properties law. Under the Act on Domestic Animal Infectious Diseases Control, chickens are livestock subject to hygiene management standards, and anyone keeping even one bird must report the number kept to the prefecture (livestock hygiene service centre) by 15 June every year. Keepers of fewer than 100 birds file a simplified report, and those shipping no birds or eggs need no attachments.
