Native breeds named in this brand's cross: Ukokkei ・ Rhode Island Red （All 38 native breeds）
This is the first jidori in Japan to bring in the Ukokkei (Silkie). The prefecture’s primary sources set no condition on where the birds are raised, how they are housed, at what density, or on what feed. The full mating scheme appears only in a diagram in the prefecture’s PDF, which cannot be read reliably, so only the sire and dam lines described in the running text are recorded.
Compared with other brands
21 chicken brands set a minimum rearing period, from 75 to 150 days. 80 days ranks 14th from the longest (4 others also use 80).
