In this paper, we consider the ethics of poultry production from different perspectives, applying both intrinsic and extrinsic ethical principles. We consider the perspectives of the animal, farmer, consumer, breeders, researchers, and policy-makers. Intrinsic ethical factors include feeling pain and experiencing suffering, self-awareness and consciousness, future planning ability, the value of being alive, and individual love of life. Extrinsic factors include human necessity and/or desire, human sensitivity to animal suffering, fear of causing brutality in humans, disapproval of other animals, and the religious status of animals. The development of systems to create more ethical poultry production systems is a work in progress, and in the evolution of ethical standards, moral progress and what can be described as more ethical poultry are evident.
