Responses of pair-housed male and female domestic chicks to the removal of a companion

Male and female domestic chicks were housed in same-sex pairs until they were tested at 11 days of age. One chick was then removed from each established pair. .. Social separation induced an overall increase in circulating corticosterone concentrations, thus...

Modification of fear in domestic chicks, Gallus gallus domesticus, via regular handling and early environmental enrichment

Regular gentle handling and environmental enrichment reduced fear responses to people. The implications of reduced fearfulness and other potential benefits of handling and enrichment procedures are discussed.

Individual perching behaviour of laying hens and its effects in cages

Caged hens spent more time on softwood perches than on hardwood, metal or plastic perches. Overall, birds spent about 25% of the day time on perches.

Differences in fearfulness indicated by tonic immobility between laying hens in aviaries and in cages

In the present study the fearfulness, as measured by the tonic immobility response, increased more with age in battery layers than in aviary layers. The more constant and lower fearfulness of birds in the aviaries suggests that with regard to...

Situational factors that influence the level of fear of human by laying hens

On the basis of the withdrawal responses of birds to an approaching experimenter, fear of humans may decline from moderate levels among birds housed in Tier 1 (bottom) to Tier 3, in both systems and then sharply increase from Tier...

Does dustbathing increase broiler productivity? In: Proceedings of the International Congress on Applied Ethology

Chickens kept in floor pens with wood shavings as litter performed five times more dust bathing behaviour when a wooden box containing peat moss was placed in the pen. The provision of peat moss dust had unexpected health benefits: Mortality...

Effects of rearing experience and stimulus enrichment on feather damage in laying hens

Rearing chicks with access to sand and peat for dustbathing reduced later tendencies to engage in feather pecking; straw enrichment [cut straw in baskets] for laying hens had a similar effect.

Feather pecking and chronic fear in groups of red junglefowl: their relationships to dustbathing, rearing environment and social status*

We feel that is useful to see feather pecking as an abnormal development of the perceptual mechanism responsible for the detection of dust for dustbathing and the exposure to salient stimuli at an early stage may be crucial. .. If...
