At this egg supplier to Nellie's Free Range Eggs, the shed was packed with 20,000 hens, which allowed each bird only about 1.2 square feet of floor space.
Hens faced constant competition for the coveted shelves and perches in the huge jam-packed shed.
Visitors found it difficult to avoid stepping on the severely crowded hens.
Despite Nellie's claims that chickens "roam where they please," access to the outdoors was restricted.
Birds could only go outside through small hatches that were reachable only by pushing past many other hens, disrupting their natural pecking order and putting them at risk of being attacked.
Some birds were missing feathers, which may have been plucked out by more dominant chickens or by themselves, as a result of stress and trauma.
