Native breeds named in this brand's cross: Aizu Jidori ・ Rhode Island Red （All 38 native breeds）
The specification sets no feed condition: its production method has three parts (chicks, rearing, final form) and the rearing part has four conditions. The mating scheme — a male line of pure Aizu Jidori × White Plymouth Rock crossed with Rhode Island Red females — appears as background, not as a production requirement.
