Reducing Laying Hen Mortality: A Welfare Priority

Mortality rates in commercial laying hen flocks are significantly above natural levels, with prevention through management and genetics offering major welfare gains.

Key Facts

Commercial laying hen mortality rates of 3-8% per flock are common in intensive systems
Feather pecking and cannibalism account for a significant proportion of hen deaths and injuries
Beak trimming reduces pecking mortality but itself causes acute and potentially chronic pain
Providing adequate enrichment and reducing stress are more welfare-positive alternatives to beak trimming
Genetics research has produced less feather-pecking prone strains in some breeding programmes

Welfare Considerations

Mortality in laying hen flocks represents both a welfare outcome measure and a welfare problem in its own right. The high rates of injurious pecking that cause many deaths result from frustration, overcrowding, and behavioural needs not met in commercial systems. Feather pecking causes pain to the target bird and, if it progresses to cannibalism, causes death. Beak trimming reduces but does not eliminate this problem while imposing its own welfare costs through acute pain and potential disruption to normal feeding and preening. The most welfare-positive approach addresses root causes through enrichment, genetic selection, and stocking density management rather than symptom management through beak trimming.

What You Can Do

Choose eggs from farms that do not practise beak trimming as a first-line management strategy
Support genetic research programmes developing low feather-pecking hen strains
Advocate for investment in housing and management improvements that reduce injurious pecking
Learn about the relationship between enrichment provision and feather pecking to make the welfare case
Support regulatory moves toward banning beak trimming with genuine improvements in management standards as prerequisite
