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

Predation in Organic and Free-Range Egg Production [PDF]
Animals, 2020 On organic and free-range poultry farms, a free-range is provided for animal welfare reasons. However, farmers report sightings of birds of prey and sometimes foxes or other predators within the free-range areas. In addition to seeing actual attacks, they also find chicken carcasses in the free-range, the deaths of which they attribute to predators. In

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.

Preference testing for UV light spectrum and intensity in laying hens
Poultry Science, 2021 Sunlight intensity and UV radiation may affect free-range hens' use of the outside range, particularly when sunlight is intense with a high UV index.

Animals, 2022 Extreme sunlight might be aversive to free-range laying hens, discouraging them from going outside. Range enrichment with artificial shelters may protect hens from sunlight and increase range use.
