Broiler breeder hens are the parents of meat chickens. They are kept on severe caloric restriction to prevent the obesity and health problems inherent in their genetics — creating a profound welfare paradox.
Broiler breeders experience chronic hunger as an inescapable consequence of their genetic selection for rapid growth. The hunger is genuine — measured through motivation testing showing extreme food-seeking behaviour. This represents one of the most pervasive yet least-discussed welfare problems in UK food production. Genetic selection for slower-growing breeds is the only long-term solution.
