Hen Nesting Behaviour Welfare | Animal Welfare Hub

Nesting is among the most strongly motivated pre-laying behaviours in hens, and the frustration of this behaviour in cage systems causes significant welfare distress.

Key Facts

Hens show increasing restlessness and agitation in the 30-60 minutes before laying
This pre-laying motivation is not reduced by providing no nest — it is intrinsic
In cage systems without nests, hens pace, attempt to hide, and show prolonged distress
Single nest box per 5-7 hens is the standard welfare recommendation
Hens lay in secluded, covered locations — uncovered or exposed nests are less used

Welfare Considerations

Pre-laying nesting motivation is one of the best-documented welfare indicators in laying hens: the behaviour sequence from increased agitation through nest inspection to laying is intrinsically programmed and not reduced by absence of the opportunity. Hens in cages without nest access show sustained distress behaviour — pacing, attempting to hide, extended wing-drooping — that lasts until laying is complete. This is measurable welfare suffering experienced by every hen in the global battery and much of the enriched cage population at every laying event throughout their lives.

What You Can Do

Choose cage-free eggs at minimum — enriched cages do not fully meet nesting needs
Advocate for nest space and design requirements in laying hen welfare standards
Support cage-free transition commitments by major retailers
Reduce egg consumption to concentrate remaining purchases at highest-welfare systems
Engage with egg industry on nest provision quality and access metrics
