Enriched colony cages represent a partial improvement over conventional battery cages for laying hens, providing more space and some behavioral opportunities, but welfare scientists debate whether they adequately meet hen behavioral needs.
Enriched colony cages occupy a contested middle ground in laying hen welfare. They represent genuine progress over conventional battery cages — hens can perch, use nest boxes, and perform some scratching — but welfare science consistently shows that the behavioral repertoire of hens in enriched cages remains severely restricted compared to free-range systems. Dustbathing is performed on wire or inadequate substrate, perch space is highly competitive, and the fundamental experience of living permanently on wire in a crowded indoor environment limits what enrichment can achieve. They are better than conventional cages but not a final destination for laying hen welfare reform.
