Farmed Laying Hen Enriched Colony Housing: Welfare Assessment

Enriched colony cages replaced conventional battery cages in the EU, but welfare concerns remain about whether enrichments are actually accessible and used by hens in these systems.

Key Facts

Enriched colony cages replaced conventional battery cages in the EU from 2012
Enriched cages provide perches, nest boxes, and scratch areas but at minimum specifications
Research shows many hens do not access enrichments due to competition from dominant birds
Keel bone fractures remain high in enriched colony systems, sometimes exceeding cage-free rates
Enriched colonies are significantly better than conventional cages but fall far short of cage-free welfare
Some retailers and food companies have committed to cage-free rather than enriched colony eggs

Welfare Considerations

Enriched colony cages represented a genuine but insufficient welfare improvement over conventional battery cages. The provision of perches, nest boxes, and scratch areas in principle addresses some behavioral needs - but the reality is that dominant hens often monopolize enrichments, leaving subordinates unable to access them. Keel bone fractures remain a major welfare issue. Cage-free systems, while not perfect, allow more natural behavior expression and movement. The welfare hierarchy for laying hens is broadly: conventional cage < enriched colony < cage-free < free-range < high-welfare free-range.

What You Can Do

Choose cage-free or free-range eggs at minimum, certified higher-welfare eggs where possible
Support food companies committing to cage-free egg sourcing
Avoid products from enriched colony systems where cage-free options are available at similar cost
Donate to organizations campaigning for cage-free as the minimum standard for laying hen welfare
