Between November and January (2014–2015), 360 fresh fecal samples (n = 60/farm) were collected from three conventional (CF) and three organic (OF) cage-free layer farms that were located in North-Western Ohio (USA). The farms housed flocks (10,000 cage-free hens each) that were 24–27 (CF-1 and OF-1), 41–44 (CF-2 and OF-2), and 62–63 (CF-3 and OF-3) weeks old, respectively (Supplementary Table S1; Supplementary Data are available online at www.liebertpub.com/fpd). All organic flocks had access to the outside of the poultry houses, and only OF-2 and OF-3 were under the same management.

Individual fresh fecal samples were collected from the floor along the same transect outline in each farm using sterile, disposable wooden spatulas directly after defecation. The samples were transferred to sterile 14mL tubes (Fisher Scientific, Inc.), which were transported on ice andprocessed in the laboratory within 6 h after collection.
