The value of environmental resources to domestic hens: A comparison of the work-rate for food and for nests as a function of time

Hens place a higher value on gaining access to a discrete nest-site prior to oviposition than they do on gaining access to food following 4 h food deprivation. (p. 39)

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...

Stereotypies in caged parrots, schizophrenia and autism: Evidence for a common mechanism

These results parallel the executive motor impairments seen in human patients, and therefore suggest that, like in human patients, stereotypy in caged parrots reflects a general disinhibition of the behavioral control mechanisms of the dorsal basal ganglia. If this result...

Stereotypic route-tracing in experimentally-cage songbirds correlates with general behavioural disinhibition

These results suggest that housing conditions that cause stereotypy thus alter many aspects of the behavioural control of subjects, mediated by altered striatal functioning. The implications for understanding stereotypies in laboratory, farm and zoo animals, and for laboratory-based behavioural are...

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.
