Ah, I should have specified the pasture-raised standards:

R 1: Pasture area

a. Must consist mainly of living vegetation. Coarse grit must be available to aid digestion of vegetation.

c. The minimum outdoor space requirement is 2.5 acres (1 hectare)/1000 birds (~109SF).

g. Birds must be outdoors 12 months per year, every day for a minimum of 6 hours per day. In an emergency, the hens may be confined in fixed or mobile housing 24 hours per day for no more than 14 consecutive days.

Free-range are only required to have 2SF and don't have a mandatory outside time.
