The result of our work shows that appropriate housing is necessary for intensively kept hens and that the housing has to correspond to the vital needs and the nature of the animals.

This is important for two reasons: a) the innate needs of the birds must be satisfied; b) for the proper development of the animal and successful egg production.

The housing facilities should allow the following functional cycles without restrictions:

Social organization: the structuring of a group or unit of animals.

Locomotion: walking, running, fluttering, flying.

Feeding behavior: search for food and water, food and water pecking, ground scratching, …

The Behavior Of Confined Calves Raised For Veal: Are These Animals Distressed?, M. Kiley-Worthington

Ethology Collection

The behavior of 12 calves confined in crates was recorded at 1-minute intervals for 12-hour periods. These recordings were made at fortnightly intervals from approximately 2 to 16 weeks of age. In all, 864 hours of observations were recorded.

The activities that were performed and the amount of time spent doing each are outlined. Circadian rhythms were controlled largely by feeding time, although there was a difference between diurnal and nocturnal behavior. Individual calves vaned tn how they adapted to the restricted environment. Individual personality profiles and data on the ontogeny of behavior under these conditions are presented.
