Five different layer housing systems were monitored during this study: conventional cage (V), enriched colony cage (E), enrichable cage (H), cage-free barn (C), and free range housing (R). Samples were collected during the laying period, starting at 22 weeks of age, every 8 weeks over the course of 10 months, for a total of 425 samples. Eggshell pool samples were prepared as described by Musgrove et al. (2005). Fecal deposits were homogenized with sterile cotton-tipped applicators. Environmental and fecal swabs were placed in 10mL of sterile phosphate buffered saline
Sampling consisted of four environmental swab locations and three types of shell pool emulsion distributed among the different housing systems. Fecal samples were collected from fecal deposits recovered from clean butcher paper placed under the cages or roosts.
