Use of pen space by broiler chickens reared at medium or very low densities

A better understanding of the motivation of broiler chickens reared indoors to go to and remain in a different part of the pen (or not) could help to provide appropriate organisation of the rearing space on farms. This study was...

Feather pecking in poultry: The application of science in a search for practical solutions

Bunches of string elicited substantially greater interest than other stimuly, including feathers, and white or yellow string was the most attractive. The birds' manipulation of the string resembled preening. Incorporating silver beads or moving devices reduced pecking. String sustained lengthy...

Effects of specific noise and music stimuli on stress and fear levels of laying hens of several breeds

The results of the present study indicate that specific noise stimulus (90 dB versus 65 dB) causes stress and fear in laying hens and specific classical music stimulus (75 dB versus 65 dB) has a negative influence on their fearfulness.

The effects of novel floorings on dustbathing, pecking and scratching behaviour of caged hens

Birds on litter or string [conventional wire wrapped with garden twine] showed a greater total duration of dustabathing than those on rubber [perforated rubber matting], and birds on litter had a richer repertoire of dustbathing elements.

Reduction in feather pecking and improvement of feather condition with the presentation of a string device to chickens

Feather pecking was virtually eliminated when the device remained in the pens from day 1 day of age or when they were presented for 4h per day.

Forced to crowd or choosing to cluster? Spatial distribution indicates social attraction in broiler chickens

At all stocking densities, chickens were more clustered than indifferent (randomly distributed) chickens, and their distribution best fitted a social attraction model in which simulated birds rejected a potential position if their distance from other birds was too great.

Effect of brooders on feather pecking and cannibalism in domestic fowl (Gallus gallus domesticus)

Twelve groups of 15 layer hen chicks were reared in pens (2.55 m2); during the first 5 weeks after hatching six pens were provided with dark brooders and six pens with heating lamps. The dark brooders completely prevented severe feather...

Development of perching behaviour in chicks reared in enriched environment

In this experiment, we studied individual differences in start of perching behaviour and if environmental enrichment enhances perching at an early age. there seems to be an association between the early start of perch use and the later use of...

A critical review of fear tests used on cattle, pigs, sheep, poultry and horses

Fear is arguably the most commonly investigated emotion in domestic animals. In the current review we attempt to establish the level of repeatability and validity found for fear tests used on cattle, pigs, sheep and goats, poultry and horses. We...
