Laying Hen Nest Box Access Welfare

Nest box access is critically important for laying hen welfare. Hens have a strong motivation to lay eggs in enclosed, private spaces.

Key Facts

Hens show high motivation to find a nest site when laying is imminent
Nest deprivation causes extreme frustration and distress observable in behaviour and stress hormones
Commercially available enriched cage and cage-free systems must include nest boxes under EU standards
Competition for limited nest boxes causes welfare problems including queue stress and floor laying
Nest box design including depth, litter type and darkness affects acceptance by hens
Pre-laying behaviour including searching lasts up to 90 minutes if suitable sites are unavailable
Adequate nest box provision significantly reduces floor eggs and associated production losses

Welfare Considerations

Nest site motivation in laying hens is one of the strongest and most reliably demonstrated welfare priorities in poultry science. Denial or inadequate provision of nest sites causes intense suffering during the laying period, repeated multiple times per week. Ensuring adequate nest box provision, quality and distribution is a fundamental welfare requirement that all commercial systems should meet.

What You Can Do

Choose eggs from higher welfare systems including free-range and organic with adequate nest provision
Ask egg suppliers about nest box ratios and design in their systems
Support welfare standards that specify minimum nest box provision and quality requirements
Reduce egg consumption and prioritise highest-welfare sources
