Broiler breeders — the parent birds that produce commercial broiler chickens — face unique welfare challenges from chronic feed restriction needed to prevent obesity and mortality from fast-growing genetics.
Broiler breeder welfare represents one of the most severe and most neglected welfare problems in animal agriculture. These birds — the parent generation that produces commercial broiler chickens — carry genetic selection for extreme growth that causes obesity, cardiovascular failure, and skeletal collapse when fed ad libitum. The industry response is chronic, severe feed restriction: birds are fed 60-80% below what they would voluntarily consume, creating a state of persistent hunger throughout their productive lives. Behavioral research documents the welfare cost clearly: persistent stereotypic pecking, aggression at feeding time, and anxiety-like behaviors are ubiquitous in restricted breeders. The solution is systemic: slower-growing broiler genetics would reduce the need for extreme restriction and improve welfare for both breeders and their commercial offspring simultaneously.
