When should forced molting (induced molting) be considered for a commercial brown layer flock, and what are the optimal local timing parameters?

Forced molting is a management tool used to rejuvenate a layer flock's reproductive system, extending their productive life into a second cycle. For commercial brown layers, molting should be considered when the flock's lay rate falls below 65-70% and shell quality begins to deteriorate, typically around 70 to 75 weeks of age. The process involves reducing day length and adjusting feed nutrition to safely trigger weight loss and feather shedding. In Pakistan, the optimal time to initiate a molt is during the moderate autumn months (October and November). Molting during extreme summer heat or winter cold puts excessive stress on the birds, leading to high mortality. Successful molting restores lay rates to 80-85% and significantly improves eggshell strength. Molting science is detailed in the Poultry Encyclopedia, specialized low-nutrient molting feeds are on Poultry Plaza, egg price spreads are on Poultry Rates, and molted layer flocks can be traded on Murghi Mandi.
