Japan's JAS standard for jidori sets four conditions: the chicks, the rearing period, the housing and the stocking density. A brand's own conditions can be stricter, or set differently. The JAS standard for jidori →
Native breeds named in this brand's cross: Shamo ・ Rhode Island Red （All 38 native breeds）
Floor housing and the density limit (10 birds per m² from 28 days) match JAS; what is stricter is the rearing period (140 days or more, against 75 under JAS). The manual also says it is desirable to keep density lower, around 5 birds per m² from 12 weeks, but that is a recommendation, not a condition.
