Research has revealed chickens to be cognitively complex animals with capacities for self-control, social learning, and time perception that have profound implications for their welfare in production systems.
Chicken cognition research has dismantled the assumption that poultry are simple, unfeeling production machines. Empathy, self-control, social learning, and numerical cognition place chickens firmly within the category of sentient, cognitively complex beings whose welfare has serious moral weight. Production systems designed around assumptions of chicken cognitive simplicity — barren, featureless environments; group sizes of tens of thousands; brief lives — are fundamentally misaligned with what we now know about the species. This knowledge creates an obligation to provide cognitively stimulating, socially appropriate environments.
