Hens that have been frozen for more than a week are still very nutritious for making soup. Generally speaking, meat should not be stored for too long, and it is best to eat it within one week. After a long time, nutrition will continue to lose. Although freezing in the refrigerator can keep fresh, it only slows down the movement of molecules and food is still rotting.
