Induced molting is a practice used in the egg industry to extend the productive life of laying hens, but the methods used — particularly feed withdrawal — cause significant suffering that more humane alternatives can avoid.
Feed withdrawal molting imposes acute suffering through prolonged starvation. Hens experiencing 5-14 days without food show intense food-seeking behavior, weight loss of 25-35%, and elevated stress hormones. More humane molting methods using low-nutrient diets achieve the same biological reset without starvation. The existence of effective alternatives makes feed withdrawal molting unjustifiable on welfare grounds — it continues where it persists because of habit and cost rather than necessity. Even the more humane alternative molting methods impose some welfare costs and the practice of extending laying hen productive life through molting extends the total duration of welfare compromise in an already challenging production system.
