Scientific research reveals that chickens have far more complex cognitive and emotional lives than commonly assumed — with major implications for how we treat them.
The persistent cultural underestimation of chicken intelligence has historically allowed their treatment in intensive farming to escape the moral scrutiny applied to mammals. The science now tells a different story. Chickens navigate complex social hierarchies, remember individual faces, show forward planning, and demonstrate clear emotional responses to positive and negative events. The gap between what we know about chicken cognition and how we treat them in intensive production is arguably the largest in all of animal welfare — involving tens of billions of birds annually. Raising public awareness of chicken cognition is a high-leverage welfare advocacy strategy.
