Brain monoamine levels and behaviour of young and adult chickens genetically selected on feather pecking
The phenotypic interrelationships between feather pecking, being feather pecked and fear criteria in White Leghorn lines selected for high and low severe feather pecking and their F2-crosses
TLDR
There is obviously no consistent relationship between feather pecking and fear in this population of laying hens and the low phenotypic correlations among the criteria confirm this conclusion.
Individual Consistency of Feather Pecking Behavior in Laying Hens: Once a Feather Pecker Always a Feather Pecker?
TLDR
Even if the development and cause of feather pecking may be multifactorial, once the behavior has been developed, some hens may persist in feather pecks and emphasis should be made to select for these hens in future breeding practices.

The control of feather pecking by serotonin.
TLDR
S-15535, a somatodendritic 5-HT-sub(1A) autoreceptor agonist, was demonstrated to be an excellent tool for reducing5-HT turnover in the forebrain of LFP and HFP chicks, and the most effective dose significantly increased severe feather-pecking behavior.

Variation in neighbouring genes of the dopaminergic and serotonergic systems affects feather pecking behaviour of laying hens.
TLDR
The annotated DRD4 in the chicken genome and re-sequenced it in 140 animals belonging to: experimental layer lines divergently selected for high and low propensity to feather pecking; the unselected founder population; and two commercial lines with low and high propensity to feathers pecking.

Chicks from a high and low feather pecking line of laying hens differ in apomorphine sensitivity
Feather pecking behavior in laying hens: hypothalamic gene expression in birds performing and receiving pecks.
TLDR
Findings may support the proposal that FP is linked to immune mechanisms and may serve as an animal model for obsessive compulsive disorder in humans and support the previously proposed hypothesis thatFP is an abnormal foraging behavior.
Changes in feather condition in relation to feather pecking and aggressive behaviour in laying hens.
TLDR
The number of severe feather pecks received was significantly related with feather damage at all ages; however, no relation with gentle feather peck received was found.
