Feather pecking (FP) is a repetitive behaviour in chickens, influenced by genetic, epigenetic, and environmental factors, similar to behaviours seen in human developmental disorders (e.g., hyperactivity, autism).

The objective of this study was to evaluate the effects of cage size on the natural behavior, serum biochemistry, production performance and hypothalamic transcriptome profiles of laying hens. A total of 360 79-week-old hens were selected and randomly assigned to three groups (with five replicates each) with different cage sizes: large cages (LCs), medium cages (MCs), and small cages (SCs). The stocking density remained consistent across all groups throughout the experimental period.

Light is an important factor affecting the feather pecking behavior in poultry. To evaluate the quality of lighting in production of a local broiler breed, this study was designed to investigate the effects of light color on the growth performance (body weight, feed conversion ratio and upper beak length), welfare parameters (walking step, plumage damage and hormone level) relating to feather pecking and their correlations. One hundred and twenty 49-day-old Youhuang broilers were randomly distributed into 3 lighting treatment groups (warm white, cold white and red) and reared for 4 weeks.

The hypothalamic-pituitary-adrenal (HPA) axis responsivity is influenced by early life experience and also modified by the environment an individual experiences as an adult. Because laying hens are transferred from rearing to laying farms at 16-18 weeks of age, they are well suited to study the interaction effect between early (rearing) and adult (laying) environments on physiology and behaviour. In the European Union, there is a move towards cage-free systems for laying hens, but globally, the majority of layers are kept in conventional or furnished cages.
