When should the transition from starter to developer feed occur for Hy-Line Brown brown layer chicks under feed consumption curve (typically 110-120g per day per hen)?

Feed transitions must be managed scientifically based on body weight rather than age alone. Transitioning Hy-Line Brown brown layer pullets too early can cause nutritional deficiencies and slow bone development, whereas transitioning too late increases feed costs and causes infestation with northern fowl mites (Ornithonyssus sylviarum). Monitoring feed consumption curve (typically 110-120g per day per hen) and using vaccinating pullets with oil-emulsion Newcastle and Bronchitis vaccines helps maintain smooth transitions.
