Hen Nesting Behaviour: Meeting a Fundamental Need

Nesting is one of the most highly motivated behaviours in laying hens. Providing appropriate nest boxes is a fundamental welfare requirement that battery cages fail to meet.

Key Facts

Hens are highly motivated to find a nest before laying — a frustrated hen will pace for hours
Pre-laying behaviour is suppressed in battery cages, causing chronic frustration
EU welfare regulations require nest boxes for laying hens in enriched cages and barn systems
Nest box preference studies show hens choose secluded, slightly darker nest areas
Proper nest box provision reduces floor eggs and associated hygiene problems in free-range systems

Welfare Considerations

The frustration of a hen prevented from nesting before laying is not a minor inconvenience — it is a profound thwarting of a biologically ingrained motivation. Research using preference testing demonstrates that hens will work harder to access a nest than for food. Battery cage systems cause this frustration to billions of birds for their entire productive lives, representing massive, ongoing preventable suffering.

What You Can Do

Choose eggs certified as free-range or certified higher welfare (RSPCA Assured)
Avoid battery-cage eggs including in processed foods where possible
Advocate for complete bans on battery cages including enriched cages
Support Compassion in World Farming cage-free campaigns
If keeping backyard hens, provide adequate nest boxes — one box per 4-5 birds minimum
