Broiler breeder hens and roosters are the parent flocks of commercial meat chickens. Their welfare is severely compromised by feed restriction programs designed to control their weight.
Broiler breeder welfare is one of the most ethically complex issues in commercial poultry farming. The birds are genetically selected to grow extremely rapidly — the same trait that makes their offspring commercially valuable. In breeders, this growth potential creates severe health problems if birds eat freely. The industry solution — chronic, severe feed restriction — creates a different but equally serious welfare problem: persistent, intense hunger lasting the entire laying life of the bird.
Research using preference testing and behavioral studies consistently demonstrates that restricted broiler breeders experience chronic hunger equivalent to starvation. They are highly motivated to eat, spend excessive time at feeders, drink more water to fill their stomachs, and show increased aggression and stereotypies driven by food frustration.
The fundamental solution is genetic — selecting for slower-growing, more robust genetics that do not require feed restriction to remain healthy. Some welfare-focused breeding programs are pursuing this approach. Short-term improvements include enrichment strategies that occupy feed-motivated behavior, and research into satiety-enhancing feed additives that reduce hunger without increasing calorie density.
