Absolutely, 4 sq per bird, maybe 3 for smaller hens, like cream legbars, and 10 in run, even tho they freerange some days, like was1-2 sq ft per bird is factory standards. Not conducive at all to a peaceful and healthy chicken flock. Here we recommend 4 sq ft in the coop and 10 sq ft in the run per bird as a bare minimum. The more space the better.
mentioned, more makes happy chickens.
