A growing body of welfare science documents the extent of suffering in broiler chicken production. Understanding the research empowers consumers and advocates to demand higher standards.
Broiler welfare science has moved from documenting obvious problems to quantifying their scale and identifying solutions. The research consistently shows that fast-growing genetics combined with high stocking densities in barren environments produces predictable, measurable welfare failures in a large proportion of birds. This is not a marginal welfare concern — lameness alone affects hundreds of millions of birds annually. At the same time, the science identifies clear paths to improvement: slower-growing breeds, lower densities, and enriched environments with natural light, perches, and litter for dust-bathing dramatically improve welfare outcomes. The Better Chicken Commitment standards, adopted by hundreds of major food companies, are directly grounded in this welfare science.
