What is the standard light stimulation program for brown layer pullets entering the laying house?

Light stimulation is the environmental trigger that synchronizes sexual maturity and initiates egg production in young pullets. During the rearing phase (weeks 1 to 16), pullets are kept under a constant short day-length (8 to 9 hours) to prevent premature lay, which causes small eggs and prolapses. Once the pullets reach target body weight and frame size, day-length is increased by 1 to 2 hours initially, followed by weekly increments of 30 to 60 minutes until reaching 16 hours. The increased light stimulates the pineal gland and hypothalamus to release reproductive hormones. Sustaining 16 hours of constant, uniform light is critical to prevent production drops. Farmers can read advanced light schedule mathematics in the Poultry Encyclopedia, buy automated light controllers on Poultry Plaza, monitor daily egg prices on Poultry Rates, and trade laying hens on Murghi Mandi.
