Abstract

Relatively little is known about the relationship between social behavior and specific cognitive abilities of the chicken. It is uncertain whether dominant birds have a cognitive advantage over subordinate birds that might facilitate their superior position in the social hierarchy. Likewise, it is...

Abstract

Ex situ conservation of threatened species may lead to behavioural adaptation, which can affect success of reintroduction attempts. In previous studies, we investigated the effects of captivity on the behaviour of red jungle fowl (Gallus gallus) and found that captive populations differed...

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

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 septal nuclei are an evolutionarily well-conserved part of the limbic system, present in all vertebrate groups. Functionally, septal nuclei are involved in many important aspects of social behavior and lateral septum is considered a node of the social decision making network, together with...

Abstract

Correctly directing social behaviour towards a specific individual requires an ability to discriminate between conspecifics. The mechanisms of individual recognition include phenotype matching and familiarity-based recognition. Communication-based recognition is a subset of familiarity-based...

Abstract

In this paper, we report on the ongoing work in our laboratories on the effect of lateralization produced by light exposure in the egg on social cognition in the domestic chick (Gallus gallus). The domestic chick possesses a lateralized visual system. This has effects on the chick's perception...

Abstract

Different lines of laying hens have undergone a strong selection pressure for productivity traits, which has been proposed as a potential cause of undesirable side effects like behavioural disorders. One reason for such behavioral changes might be due to energy trade-offs, as high productive laying ...

Abstract

Many traits associated with domestication are suggested to have developed as correlated responses to reduced fear of humans. Tameness may have reduced the stress of living in human proximity and improved welfare in captivity. We selected Red Junglefowl (ancestors of all domestic chickens) for four...

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...
