Broiler breeder chickens are chronically underfed to prevent the obesity that their genetics predispose them to, creating a welfare paradox at the heart of modern poultry production.
Feed restriction in broiler breeders represents one of the most entrenched welfare problems in commercial poultry production. The birds are genetically selected for rapid growth in broiler offspring, but this same genetics makes breeders prone to skeletal problems and cardiovascular failure at ad libitum intake. The result is that billions of breeding birds experience chronic hunger throughout their productive lives. This is not a husbandry failure but a designed feature of the system. Transitioning to slower-growing breeds is the only structural solution, though it comes with economic costs the industry is reluctant to absorb.
