Bull's eggs and goat's eggs are both good for the kidneys, but there is no conclusive evidence that one egg is better than the other as to which one is most nourishing to the kidneys.

Bull's eggs contain a lot of protein and nutrients, which can play a good role in nourishing. Sheep eggs, on the other hand, are rich in protein and phospholipids, which have a good nourishing effect on the human body, and the nutrients in sheep eggs have a good effect on strengthening the body's immunity and preventing diseases.

Therefore, it is recommended to consume cow eggs and sheep eggs appropriately in your daily diet to promote good health.
