Providing environmental enrichment to commercial poultry addresses behavioral frustration that is ubiquitous in barren production environments, with documented welfare and productivity benefits.
Poultry enrichment is welfare science in action: providing even simple objects — string, pecking blocks, perches, substrate for dust bathing — measurably reduces frustration, injury, and cortisol levels in commercial flocks. The behavioral needs of chickens are strong and unmet in barren environments: the urge to dust bathe is so powerful that birds perform the behavior on bare wire without substrate. Feather pecking and cannibalism — serious welfare problems in commercial flocks — are largely driven by frustration from unmet behavioral needs and are substantially reduced by enrichment provision. Enrichment is one of the most cost-effective welfare improvements available in poultry production.
