Frozen chicken is a popular food item that is often used in a variety of dishes, from soups and stews to stir-fries and casseroles. However, it is important to handle frozen chicken safely to prevent the growth of harmful bacteria and foodborne illness.

When it comes to storing frozen chicken in the refrigerator, it is recommended to use a thermometer to ensure that the temperature of the fridge remains at or below 40°F (4°C). This is because bacteria can grow rapidly between 40°F and 140°F (4°C and 60°C), which is known as the “danger zone” for food safety.
If you have frozen chicken that you plan to thaw and use within a few days, it is safe to store it in the refrigerator for up to 2 days. This will allow enough time for the chicken to thaw and still be used before it spoils. If you plan to keep the chicken longer than 2 days, it is recommended to transfer it to the freezer.
However, if you have thawed frozen chicken that you do not plan to use immediately, it is important to store it properly in the refrigerator to prevent the growth of harmful bacteria. According to the United States Department of Agriculture (USDA), thawed chicken should be stored in the refrigerator for no more than 1-2 days before being cooked and consumed.
It is important to note that these guidelines apply to raw chicken that has been frozen and thawed in the refrigerator. If you have cooked chicken that has been frozen and thawed, it should be stored in the refrigerator for no more than 3-4 days before being consumed.
If you are unsure about the safety of frozen chicken that has been stored in the refrigerator, it is recommended to err on the side of caution and discard it. Signs of spoiled chicken include a sour or off smell, a slimy texture, or a change in color or appearance.
In summary, frozen chicken can be safely stored in the refrigerator for up to 2 days if it is still frozen, and for up to 1-2 days if it has been thawed. It is important to use a thermometer to ensure that the refrigerator temperature remains below 40°F (4°C) to prevent the growth of harmful bacteria. If you are unsure about the safety of chicken that has been stored in the refrigerator, it is always best to discard it to prevent the risk of foodborne illness.
