Effects of environmental enrichment and gentle handling on behaviour and fear responses of transported broilers
Enriched/handled birds were more active in their home pens than control animals. ..The most fearful birds were those which had been enriched [fabric squares, plastic rings, grass, perches, etc.] and handled, whilst the least fearful bird were enriched but not...

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...

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.

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.

Read MoreDifferences 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...

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...

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...

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.
