Chicken knees are the joints between the chicken’s drumstick and thigh. They are a good source of collagen, which is a type of protein that helps to keep your skin, hair, and nails healthy. Chicken knees are also a good source of calcium and phosphorus, which are important for strong bones and teeth.

A quarter thigh is a cut of chicken that consists of the thigh and drumstick of a chicken, with the bone in. It is a dark meat cut, and is typically sold skin-on. Quarter thighs are a relatively inexpensive cut of chicken, and are often used in dishes such as roasted chicken, chicken soup, and chicken pot pie.
