Assessing laying hen welfare requires validated measures capturing both the absence of suffering and the presence of positive states. Modern welfare assessment tools transform how farms are evaluated.
Welfare assessment for laying hens has moved beyond housing-type classifications toward direct measurement of welfare outcomes on individual and flock levels. This shift is significant because housing type alone is an insufficient predictor of welfare: a well-managed aviary system may produce better welfare outcomes than a poorly managed free-range system. Animal-based indicators provide a more honest picture of actual welfare delivered. The challenge is incorporating positive welfare measures that capture hen experience beyond the absence of obvious suffering. Hens that actively use dust bathing areas, perch at night, and show low fearfulness scores are demonstrably experiencing better welfare than those in the same housing without these behaviours.
