Uncooked chicken can safely stay in the fridge for only one to two days after its sell-by date before its condition starts to deteriorate. Raw chicken can last longer when it is placed in a freezer, which increases its usage time to up to nine months.
Uncooked chicken typically has a longer shelf life when it is kept in its original packaging while it is being refrigerated. When chicken is cooked, its shelf life when refrigerated increases from a maximum of two days to a maximum of four days. However, cooked chicken has a shorter freezer shelf life of only four months.
