Broiler breeder chickens — the parents that produce commercial meat chickens — are kept chronically hungry to prevent the obesity and health failures that would otherwise occur in their fast-growing genetics.
Broiler breeder welfare represents one of the most ethically complex issues in commercial poultry production. Birds are deliberately kept in a state of chronic hunger — not because of negligence or cruelty, but as an inherent consequence of the genetics selected for their offspring. A broiler breeder given unrestricted access to food would develop life-limiting obesity and skeletal collapse. The welfare solution requires addressing the underlying genetics: developing commercial broiler lines from parents that can maintain healthy body condition without restriction. Until then, some farms use more sophisticated feeding systems including total mixed ration approaches that reduce motivational frustration while maintaining necessary intake restriction. This issue illustrates how genetic selection decisions upstream create irreducible welfare costs downstream.
