Broiler chickens are the most numerous farmed animals on Earth, and significant welfare improvements are achievable without major cost increases.
Fast-growing broiler breeds experience chronic pain from lameness caused by their rapid skeletal growth. Studies show they spend most of their time lying down due to leg pain by their final weeks. Switching to slower-growing breeds, reducing stocking density, and providing enrichment like perches and pecking objects significantly improves welfare at relatively modest cost increases.
