Abstract

Although social behaviour is a major factor affecting the coping of poultry in production environments little is known about how it has been affected by intensive selection processes in fowl. We attempted to clarify selection effects on overall repertoire and occurrence of different social...

Abstract

Social preferences of familiar over unfamiliar social stimuli in chicks may be used to measure sociality, a characteristic important for the welfare of poultry in commercial production. We studied social preferences and reaction to strangers in young White Leghorns and red jungle fowl (Gallus...

Abstract

Social coherence tendency is an important behavioural characteristic in young fowl related to an underlying social motivation that can be modified by breeding. Our aim was to investigate if selection for productive traits in a certain White Leghorn layer strain has influenced different components...

Abstract

When thwarted in a behaviour, laying hens show an increase in stereotyped pacing, displacement preening and a specific vocalization known as the gakel-call. How these behaviours, which might serve as indicators of welfare, are influenced by social factors is not yet known. In this study, the effect ...

Abstract

Despite attempts to relate vocalization of animals to their welfare status, very little is known in farm animals and in precocious birds. We analysed vocal expressions of 50 chicks during step by step social isolation. 91.20% of the recorded vocalisations (n=21 583 calls) consisted of four main...

Abstract

Three different breeds of poultry, representing different degrees of domestication, were observed in semi-natural conditions in order to study differences in foraging behaviour, activity levels and social behaviours which could be caused by correlated responses to selection for increased...

Abstract

The effects of competition and disturbances on nest-site selection were studied in commercial laying hens. Hens were housed in 16-litter floor pens (15, 30, 60 and 120 hens per group × 4 replicates) and the levels of aggression and disturbances were compared between nest boxes and pen corners. The...

Abstract

42 groups of 30 laying hen chicks were observed for feather pecking under various housing conditions in Switzerland, for the first 7 weeks of life. It is concluded that in contrast to previous experiments, the presence of an appropriate substance for dust bathing, for example sand, does little to...

Abstract

The effect of a drinking companion on conspecifics was investigated using domestic hens (Gallus gallus domesticus). The two aims of the investigation were firstly to see whether drinking is sensitive to social facilitation, and if so, to see whether it follows the same pattern as that of feeding,...
