Broiler breeder hens and roosters — the parents of commercial meat chickens — face a specific and severe welfare problem: chronic hunger. Understanding this hidden welfare crisis is essential for comprehensive poultry welfare reform.
Broiler breeder welfare represents a fundamental ethical problem created by selective breeding: the genetic traits selected for market performance in offspring are incompatible with the welfare of breeding adults. The chronic hunger induced by standard feed restriction is not a mild discomfort but a sustained, significant welfare cost experienced by every bird in every broiler breeder flock globally — approximately 600 million birds annually. Research using conditioned place preference and motivation tests confirms that feed-restricted broiler breeders are genuinely hungry, not merely behaviourally frustrated. The stereotypic pecking and foraging behaviour observed in restricted birds — continuing long after food access ceases — indicates a motivational state analogous to obsessive food-seeking in chronically food-deprived animals. The long-term solution requires genetic selection away from extreme growth rates in parent lines — a position now adopted by major welfare organisations but resisted by industry because slower-growing offspring would reduce commercial efficiency. In the interim, qualitative feeding strategies represent the most meaningful welfare improvement available within the current genetic system.
