Free-range use and intestinal parasites in organic/free-range laying hens [PDF]
Journal of Applied Poultry Research, 2023 SUMMARY: Intestinal parasites are commonly found in non-cage laying hens. Some of these parasites reduce welfare and performance. Anthelmintics are not always effective and may lead to residues in eggs and in the environment. The aim of this study was to

Factors affecting ranging behaviour in commercial free-range hens [PDF]
World's Poultry Science Journal, 2016 Many studies have assessed use of the outdoor ‘range’ area on free-range laying farms, and have revealed that percentage range use at any one time rarely exceeds 50% of the flock, and is sometimes below 10%.

Enhancing Range Use in Free-Range Laying Hen Systems: The Impact of Vegetation Cover over Time [PDF]
AnimalsOutdoor ranges in free-range laying hen systems are often underutilised, likely due to their open, uncovered nature. Given that the domestic chicken’s ancestor inhabits forests with high canopy cover, similar habitat preferences can be expected.
