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

The presence of eavesdroppers within a communication network can increase the costs associated with signalling. Hence, selection should favour the ability to vary signal structure with social context. One possible mechanism is the flexible combination of the components that form a multimodal...

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

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,...
