Induced molting programs used to extend laying hen production cycles have significant welfare implications that differ between starvation-based and humane alternatives.
Induced molting welfare depends entirely on the method used. Feed withdrawal programs that starve hens for up to two weeks represent severe welfare harm: prolonged intense hunger is one of the most aversive experiences for chickens, causing extreme stress responses, food-seeking stereotypies, and associated suffering. The rationale that starvation is required for effective molting has been disproved by research showing alternative low-nutrient diets achieve equivalent molting results without starvation. This evidence removes the productivity justification for starvation molting, leaving only welfare-harmful practice that regulatory pressure and higher welfare certification standards are progressively eliminating. Consumers choosing higher welfare certified eggs support the production systems that do not use starvation-based molting.
