Scientific research has revealed chickens to be far more cognitively and emotionally sophisticated than previously recognised, with profound implications for how we justify and reform the conditions of their intensive farming.
Chicken cognition research has transformed the scientific and ethical landscape for farmed bird welfare. These findings mean that conditions in intensive poultry farming — where billions of birds are kept in barren environments with little ability to express natural behaviours — inflict welfare harm on animals with emotional lives, social bonds, and perceptual sophistication that most people do not associate with chickens. A hen that shows empathy for her chicks experiences something when separated from them. Research findings that chickens can anticipate the future mean that chronic stress about inadequate conditions may persist across time rather than being purely moment-by-moment. This science supports significantly higher welfare standards than current norms.
