Japanese quail are widely farmed for eggs and meat in intensive systems that raise welfare concerns about stocking density, beak trimming, and behavioural restriction.
Quail in intensive systems cannot perform natural ground-foraging and dustbathing behaviours. High stocking densities cause chronic stress, competition, and aggression. The compact nature of quail production makes individual welfare assessment challenging. Research using quail as models for poultry welfare has identified that welfare indicators including corticosterone levels are elevated at high stocking densities. Welfare improvements including enriched substrates and reduced densities are transferable from research to production settings.
