Level of stress in relation to emotional reactivity of hens
It can be concluded that such behaviours as feather preening and latency until tonic immobility occurs can be indicators of stress in laying hens.
Exposure to Increased Environmental Complexity during Rearing Reduces Fearfulness and Increases Use of Three-Dimensional Space in Laying Hens (Gallus gallus domesticus)
The hypothesis that laying hens reared in a complex aviary system with exposure to mild intermittent stressors would be less fearful, less sensitive to stress, and would use elevated areas of the pen more often as adults than hens raised in a barren cage environment is supported.
An attention bias test to assess anxiety states in laying hens
An attention bias test could be used to assess anxiety in hens and behavioral responses of hens may vary depending on their age or test environment familiarity, thus further refinement of the test is required.
Stocking Density Affects Stress and Anxious Behavior in the Laying Hen Chick During Rearing
The present study evaluated anxious behavior and corticosterone levels, a hormone involved in the stress response, during the first 10 weeks of laying hen chicks housed under three different crowding conditions: undercrowding, conventional crowding, and overcrowding, finding that overcrowded chicks displayed more anxious behavior compared to underc Crowding chicks.
Application of open field, tonic immobility, and attention bias tests to hens with different ranging patterns
It is suggested that latency to eat in a novel arena without any alarm call playback is an informative measure of anxious state that can be applied to all hens but consideration must be made of potential differences in food motivation.
Multidimensionality of fear in captive greenfinches (Carduelis chloris)
The findings of this experiment challenge the concept of a single internal variable responsible for fearfulness and support the proposed multidimensional nature of fear responses.
Fear, stress, and feather pecking in commercial white and brown laying hen parent-stock flocks and their relationships with production parameters.
This is the first study to associate levels of fear and CORT to production in commercial PS flocks and assesses genotype and group size effects.
Psychological and Physiological Stress in Hens With Bone Damage
This study provides the first evidence of a relationship of bone health with fear, sociality, and stress response and shows no association between open-field fear level and fear behavior, CORT concentration, or body weight on the one hand and bone damage at 29 wa on the other.


Higher inherent fearfulness potentiates the effects of chronic stress in the Japanese quail
Effects of genetic group selection against mortality on behavior and peripheral serotonin in domestic laying hens with trimmed and intact beaks
Social stress in laying hens: differential dopamine and corticosterone responses after intermingling different genetic strains of chickens.
The results indicated genetic selection for production and survivability differentially altered DA and CORT systems in response to social stress, which suggested HGPS hens had a better coping capability to social Stress, which might have been responsible for their higher productivity and survivable.
Chronic immobilization stress alters aspects of emotionality and associative learning in the rat.
The authors present two experiments examining emotional and learned responses to CIS, and report significant effects of CIS on aggression, inhibitory avoidance, escape, as well as learned aspects of fear in rats.

An emotional trait in infancy that predicts an early death and an associated neuroendocrine trait in adulthood that is a potential mechanism underlying the relationship between behavioral style and longevity are identified.
