Broiler breeder chickens are feed-restricted throughout their lives to prevent the obesity and reproductive failure caused by their genetics; this causes chronic hunger that represents a serious and underacknowledged welfare problem.
The feed restriction of broiler breeders represents one of the most ethically troubling practices in poultry production, precisely because it is essential to the commercial system rather than an optional cruelty. Birds bred for maximum growth rates face obesity, cardiovascular disease, and reproductive failure at normal feeding levels — yet restriction causes chronic hunger. This is a structural welfare problem requiring genetic solutions, not simply management improvements.
