Ecological aspects of chicken husbandry – Interaction between environmental condition, behavioural activity of hens and quality of deep litter

Under low light conditions behaviour activity decreases but feather pecking increases strongly. Feather pecking therefore can be interpreted as a deficiency in light stimuli for the initiation of normal behaviour patterns in a deep litter system.

Effects of pecking incentives during rearing on feather pecking of laying hens

The provision of grain or other objects - which encourage pecking behaviour - during rearing reduces the incidence of feather pecking when the animals are mature.

Welfare of laying hens in cages and alternative systems: Environmental, physical and behavioural aspects

There are many different characteristics of housing systems which affect the welfare of laying hens, particularly because welfare itself has many diverse aspects. When cause and effect relationships between systems and welfare are assessed, it is evident that no system...

Effects of perches in laying cages on welfare and production of hens

Caged hens spent 25 to 50% of the light period and around 85% of the dark period roosting on perches. Perches with a rectangular cross-section caused less damage to the feet of birds than those with a circular cross-section.

Environmental enrichment influences on body weight, feathering, food condition and behaviour of caged white leghorn hens

Novel objects, providing a diversity of tactile, visual, and auditory stimuli, hung in front of one row of caged within reach of the caged hens, improved foot and feather conditions. Enriched hens were more confident in a novel environment.
