Frozen chickens and turkeys should be thawed in the refrigerator. This prevents all parts of the bird from getting warm enough to encourage the growth of spoilage bacteria before the entire birds is thawed completely. Depending on the size of the bird, two or three days may be required to complete the thawing process. If faster thawing is necessary birds can be immersed in cold water. Directions on the label concerning thawing should be followed.
