Induced molting forces laying hens into a new production cycle by triggering feather loss. Traditional food-withdrawal molting causes extreme suffering, and alternatives exist but are inconsistently adopted.
Feed-withdrawal molting caused extreme suffering: hens rapidly lost 25-35% of body weight while experiencing intense hunger, immune suppression, and increased Salmonella shedding. The scientific welfare consensus that this practice caused unacceptable suffering drove its phase-out in the US industry after the United Egg Producers committed to alternatives in 2005. However, the transition to non-feed-withdrawal alternatives has been incomplete and inconsistently enforced in some markets. Even alternative molting programs involve significant physiological stress — the process of reversing reproductive function and regrowing feathers is metabolically demanding. The EU decision to prohibit molting entirely and cull flocks represents the highest welfare standard. The welfare of hens in their post-molt second laying cycle must also be considered — molted hens show higher rates of osteoporosis and immune compromise.
