Broiler breeders — the parent birds that produce commercial broilers — are subjected to chronic hunger to prevent obesity that would impair reproduction, representing a significant hidden welfare problem.
Broiler breeders experience chronic hunger throughout their reproductive lives as a deliberate management strategy. Research shows these birds are in a persistent state of hunger that motivates sustained food-seeking behaviour. They demonstrate anticipatory aggression around feeding times, drink excessive water, and show floor-pecking for non-existent food — all signs of food motivation that cannot be satisfied. This represents a systematic welfare compromise built into the genetics of commercial broiler production.
