Enhancing Range Use in Free-Range Laying Hen Systems: The Impact of Vegetation Cover over Time [PDF]

Animals
Outdoor 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.

luox: novel validated open-access and open-source web platform for calculating and sharing physiologically relevant quantities for light and lighting [version 2; peer review: 2 approved]

Wellcome Open Research, 2021
Light exposure has a profound impact on human physiology and behaviour. For example, light exposure at the wrong time can disrupt our circadian rhythms and acutely suppress the production of melatonin.

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.

Commercial Free-Range Laying Hens’ Preferences for Shelters with Different Sunlight Filtering Percentages

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.
