1. The inability of hens to express normal nesting behaviour in battery cages results in frustration, manifesting itself as stereotyped pacing. Frustration can cause hens to retain their eggs beyond the expected time of lay, resulting in an extra-cut

To determine whether hens find the flicker of some fluorescent light aversive, the preferences of 16 light hybrid laying hens for light produced by high-frequency or low-frequency compact fluorescent lamps were tested individually in a two-room testi

Domestic fowl were deprived of the opportunity to perform litter-related behaviour for three or four days and were tested in a Y-maze (which they had previously been trained to run) for their ability to associate a coloured cue with gaining access to

An experiment was designed to investigate the reasons for the decrease in fertility which commonly occurs in broiler breeder domestic fowl in the later part of the laying year. Male broiler breeders were penned individually with 15 females and fed se

Production and behavioral measures were recorded to determine the level of stress and pain associated with tail docking adult dairy cows with a rubber ring. The possible advantages of using an epidural anesthetic were also examined. Sixty-four lactat

We tried to determine the preferred group size of hens in single and mixed-sex flocks by allowing groups to form in a setting that we predicted would facilitate segregation. Two flocks of 50 medium hybrid hens and two flocks of 50 hens plus ten roost

The reserpine derivative, ‘Pacitran’, was tested for its effects on stereotyped movements induced by frustrating the attempts of Leghorn hens to obtain food. In one experiment, the drug delayed the onset of stereotyped movements. In a second expe

The results from the first experiment showed that the responses of adult hens towards human beings were very resistant to modification. The typical responses of two stocks of domestic fowl, one docile and one flighty, were generally unaffected by ass

This paper describes the reproductive behaviour of a population of domestic fowl established on an uninhabited island off the coast of Scotland in the spring of 1975. Nest site selection, nesting, laying and incubating behaviour were studied and comp
