The effect of a sudden change in floor type on pecking behaviour in chicks

Feather pecking is to be considered as redirected ground pecking. Slatted floors appear to contribute to feather pecking. Floors without litter appear to stimulate feather pecking or, in other words, the redirection of ground pecking. .. In order to prevent...

The performance of nest building by domestic hens: is it more important than the construction of a nest?

Nest-building behaviour was not [emphasis added] inhibited by the existence of a preformed nest. This finding does not support the hypothesis that animal welfare in intensive housing can be safeguarded merely by providing that environment which would have been created...

Filial imprinting, environmental enrichment, and music application – Effects on behavior and performance of meat strain chicks

In conclusion, these preliminary studies on the combined effects of filial imprinting, environmental enrichment, and music on the performance and behavior of meat type chicks, suggest the possible benefits of these procedures, such as reduction of stress behavior [fear response]...

Nest site selection and nest-building behaviour in domestic fowl

It is more important for hens to have a nesting site with a substrate that can be moulded with the body and feet than one that can be manipulated with the beak. ... The hen has some 'need' to perform...

Preferences of hens for shape and size of roosts

It is concluded that hens prefer roosts that are large [5 cm diameter] rather than small, and square or round rather than triangular in shape.

Limb bone strength and movement in laying hens from different housing systems

The amount of movement possible for laying hens in battery cages was insufficient to avoid the development of osteopenia and consequent bone fragility.

Perch use, plumage and foot condition and bone strength in caged hens

Caging laying hens restricts movement, reduces bone strength, and affects foot conditions and plumage quality. This experiments determined whether providing perches influenced these variables. There were five treatments: front perch, rear perch, front + rear perch, long perch and control...
