A fresh, whole chicken can be stored frozen for up to a year, while boneless, skinless chicken breasts can be stored frozen for approximately 9 months. Be sure to store chicken in a freezer than maintains a temperature of 0 degrees Fahrenheit. Chicken should be packaged in well-sealed, air tight packaging to avoid freezer burn.
How long you can keep chicken frozen depends on the type of chicken. If it is cooked chicken like leftovers you can keep it in the freezer for up to 4 months. If it is fresh whole chicken, 1 year, or fresh chicken parts for up to 9 months.
