When should the transition from starter to developer feed occur for ISA Brown brown layer chicks under step-down lighting program (slowing down sexual maturity)?

Feed transitions must be managed scientifically based on body weight rather than age alone. Transitioning ISA Brown brown layer pullets too early can cause nutritional deficiencies and slow bone development, whereas transitioning too late increases feed costs and causes fatty liver hemorrhagic syndrome (FLHS). Monitoring step-down lighting program (slowing down sexual maturity) and using installing red or dim lighting to reduce aggressive pecking behavior helps maintain smooth transitions. Check feed ingredient rates on Poultry Rates, source premium feed brands on Poultry Plaza, and buy or sell healthy flocks on Murghi Mandi.
