Broiler chickens raised for meat have limited behavioral opportunities in conventional systems; enrichment significantly improves welfare without major cost increases.
Modern broiler chickens have been selectively bred for growth rates that outpace their skeletal and cardiovascular development. Many birds experience chronic lameness and cardiac stress by the time they reach slaughter weight. Even within existing production systems, simple enrichment interventions — perches, pecking objects, and improved litter quality — measurably reduce fearfulness and increase activity. Transitioning to slower-growing breeds with enriched environments and better stocking densities represents the highest-impact improvement available to the broiler industry.
