 There is little change in nutrient value of chicken during freezer storage.For optimal quality, however, a maximal storage time in the freezer of 12 months is recommended for uncooked whole chicken, 9 months for uncooked chicken parts, 3 to 4 months for uncooked chicken giblets, and 4 months for cooked chicken.Freezing does not usually cause color changes in poultry, but the bones and the meat near them can become dark.
