In a study over 90 weeks of 150 000 hens kept in a Big Dutchmen enriched system, researchers found better performances than in a Hy‐Line standard system. Hens in the enriched system performed better in mortality rates, egg production, and average weight. There was no noted improvement in feed intake or feed conversion in the enriched system.
