Positive Welfare Indicators for Laying Hens Advanced

Developing and validating positive welfare indicators for laying hens moves beyond absence-of-suffering metrics to assess genuine positive states including pleasure, comfort, and engagement.

Key Facts

Positive welfare indicators for hens include dust bathing frequency, perch use, and play behaviour
Comfort behaviours like wing stretching, preening, and sunbathing indicate absence of aversion
Social agonistic interactions that are brief and ritualised indicate stable, functional flock dynamics
Hens with access to outdoor space show distinct positive affect in open-field behavioural tests
Laying behaviour, including nest selection effort, reflects hens' capacity for motivated positive states
Cognitive bias tests can detect positive or negative affective states in hens at flock level
Positive welfare indicators are increasingly incorporated into certification standards alongside clinical measures

Welfare Considerations

Measuring positive welfare in laying hens represents a shift from simply ensuring animals do not suffer to actively ensuring they experience good lives. Hens have rich behavioural repertoires - foraging, dust bathing, perching, and social interaction - that they are strongly motivated to perform. Systems that allow these behaviours produce demonstrably better welfare outcomes.
