Influences of Maternal Care on Chicken Welfare

This review covers the literature demonstrating the important features of maternal care in domestic chickens, the behavioural consequences of deprivation and the welfare implications on commercial farms, and suggests ways to use research in natural maternal care to improve commercial chick rearing practice.

Socially-mediated arousal and contagion within domestic chick broods

It is demonstrated the co-occurrence of socially-mediated behavioural and physiological arousal and contagion; component features of emotional contagion.

Understanding Chicks’ Emotions: Are Eye Blinks & Facial Temperatures Reliable Indicators?

In commercial farming systems, chicks are reared without a mother. This absence of maternal influence can cause welfare problems when the chicks become older. Chicks imprint on their mothers they are

The demonstrated complexity in mental abilities of chickens raises the question of whether the view and treatment of chickens should be re-frame as both a research animal and a production animal.

Physiological resonance between mates through calls as possible evidence of empathic processes in songbirds

Sophisticated Fowl: The Complex Behaviour and Cognitive Skills of Chickens and Red Junglefowl

The realisation that domestic chickens, the authors' most abundant production animal, are behaviourally and cognitively sophisticated should inspire increased use of them as both research and hobby animals, as well as improvements in their unfortunately often poor welfare.

Effects of Dark Brooder Rearing and Age on Hypothalamic Vasotocin and Feather Corticosterone Levels in Laying Hens

The use of brooders tended to increase AVT expression in the anteromedial pre optic nucleus and supraoptic nucleus, an indication that dark brooder rearing may affect physiological responses regulated by these areas, and pleads for the use of dark brooders in on-farm situations.

Hypothalamic vasotocin and tyrosine hydroxylase levels following maternal care and selection for low mortality in laying hens

The hypothalamic dopaminergic and vasotinergic systems are altered in hens following genetic selection or maternal care, indicating a potential role for these systems in feather pecking.

No Evidence for Emotional Empathy in Chickens Observing Familiar Adult Conspecifics

The capacity of animals to empathise is of high potential relevance to the welfare of group-housed domestic animals. Emotional empathy is a multifaceted and multilayered phenomenon which ranges from

Avian maternal response to chick distress

The pronounced and specific reaction observed indicates that adult female birds possess at least one of the essential underpinning attributes of empathy, as indicated by the results of the current study.

The maternal feeding display of domestic hens is sensitive to perceived chick error

It is suggested that hens are sensitive to perceived chick error, and that the costs of increased display intensity are balanced by the benefits of attracting chicks to more profitable food items.

Empathy: Its ultimate and proximate bases.

The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature and can also predict a variety of empathy disorders.
