Abstract excerpt

Feather pecking is a well known problem in flocks of laying hens. It is partially controlled by genetics. Fear is frequently reported to be related with feather pecking. The present study reports the result from a quantitative genetic analysis of feather pecking and three fear test traits in laying hens. Fear was recorded by the tonic immobility test, the open field activity and the emergence box test. These were...
