Nest Box Provision for Laying Hens

Providing adequate nest boxes for laying hens is essential to meet their strong pre-laying behaviour motivation and prevent floor laying and egg breakage.

Key Facts

Laying hens have a strong nesting motivation that peaks in the hours before laying
Insufficient nest box provision causes queue-forming, aggression, and floor laying
EU regulations require minimum nest provision but research suggests current requirements are insufficient
Hens show clear preference for enclosed, dimly lit nesting areas with appropriate substrate
Nest box design, location, and availability significantly affect hen welfare during the laying period

Welfare Considerations

Hens denied access to adequate nesting space show clear signs of frustration including restlessness, vocalisation, and stereotypic pacing before laying. This frustrated nesting motivation represents genuine suffering in birds that cannot satisfy a strong innate drive. Providing more nest boxes than the regulatory minimum, with appropriate design and substrate, dramatically reduces frustrated nesting behaviour. Egg collection frequency also affects nest availability and box hygiene.

What You Can Do

Choose eggs from systems with demonstrated nest provision beyond minimum requirements
Support welfare certification schemes that specify nest design and availability standards
Learn about hen nesting behaviour when evaluating laying hen welfare claims
Advocate for evidence-based nest provision requirements in laying hen welfare legislation
Reduce egg consumption or substitute plant-based alternatives to lower demand on intensive systems
