Scientific research has demonstrated that chickens possess sophisticated cognitive and emotional abilities that profoundly challenge assumptions underlying their treatment in agriculture.
The cognitive and emotional complexity of chickens makes the conditions of industrial poultry production ethically indefensible by the same principles we use to evaluate the welfare of dogs or other animals we recognize as sentient. Chickens that experience emotions including fear frustration and apparent contentment are not simply food-producing machines. The scientific evidence demands a fundamental reassessment of how we justify their treatment in agriculture.
