[Effect of the laying nest on cortisone levels in the plasma of laying hens prior to oviposition].
The effects of a laying nest on egg-laying behaviour and plasma corticosterone levels are described. Three causes of increasing corticosterone levels are discussed: (1) an increase during egg-laying behaviour; (2) an increase during oviposition; (3) an increase due to removal of the laying nest.
