Ready-Prepared Chicken: When purchasing fully cooked rotisserie or fast food chicken, be sure it is hot at the time of purchase. Use it within 2 hours or cut it into several pieces and refrigerate in shallow, covered containers. Eat within 3 to 4 days, either cold or reheated to 165 °F (73.9 °C). It is safe to freeze ready-prepared chicken. For best quality, flavor, and texture, use it within 4 months.
