Headshaking in fowls: the effect of environmental stimuli
Contributor(s):: Hughes, B. O.
The incidence of headshaking in domestic fowls is influenced by both social and environmental factors; it was more frequent in larger groups and in subordinate birds, and it could be greatly increased by exposure to disturbing stimuli. The findings are not readily explained by earlier suggestions...

Inhibition of agonistic acts between domestic hens by a dominant third party
Contributor(s):: Ylander, D. M., Craig, J. V.
In a study of the inhibitory effects of adult males and of dominant females on frequency of agonistic acts between pairs of feeding hens, three flocks were used in each of two experiments. When a cock was in their immediate presence, hens had only 5 peck-avoidances in 24 10-minute trials; when he...

Interfacing genetics, behavior and husbandry in White Leghorns presented with E. coli challenge
Contributor(s):: Mauldin, J. M., Siegel, P. B., Gross, W. B.
Female fowls from the 3rd and 4th generations of lines which had undergone selection for persistence and non-persistence of antibody production to sheep erythrocytes were reared as floor flocks to 134 or 242 days of age, and were then reared singly in cages. At 295 or 394 days of age, females...

Observations on group mating of bulls at pasture
Contributor(s):: Blockey, M. A. de B.
Five experiments were carried out on the socio-sexual behaviour of beef bulls mated as a group to a herd of cows: (1) to predict the social dominance order in grouped bulls, (2) to investigate by computer simulation the group sizes needed to estimate accurately social dominance order, (3) to...

Patterns and frequency of social interactions in young grazing bulls and steers
Contributor(s):: Hinch, G. N., Lynch, J. J., Thwaites, C. J.
Two herds of Hereford cattle, each containing bulls and steers, were observed at ages between 10 and 18 months. Bulls showed higher frequencies of all interactions except grooming and running, but the differences between bulls and steers were significant only at ages greater than 14 months. A...

Position in the peck order and response to human threat in domestic fowl
Contributor(s):: Syme, L. A., Syme, G. J.
Three groups of 8 domestic fowl (two all male, and one all female) were subjected to repeated physical threat by a human in group and individual conditions. The last bird to retreat in the group-testing (longest latency for individual measures) and the first (shortest latency) to approach after...

Relationship between production factors and dominance in White Leghorn hens in a study on social rank and cage design
Contributor(s):: Cunningham, D. L., Tienhoven, A. van
The effects of social rank and cage shape on feeding frequency, weight gain, production rate, egg size, shell strength and overt aggressive activity were determined for layers housed 6 per cage in deep and shallow cages. Social rank significantly affected feeding frequency, production rate, egg...

Social and spatial organization of male behaviour in mated domestic fowl
Contributor(s):: Pamment, P., Foenander, F., McBride, G.
Observations were made of male spacing, mating and agonistic behaviour in 2 pens of mated domestic fowl. In both pens, site attachment was found, with a bunching of observations for cocks living close to a wall. High-ranking males appeared to move over smaller areas than did low-ranking males. A...
