What does a little spot of blood in chicken egg mean?

A small spot of blood in a chicken egg is commonly referred to as a "meat spot" or a "blood spot." It occurs due to the rupture of a small blood vessel in the hen's ovary or oviduct during the egg formation process. These spots consist of blood cells and are completely harmless and safe to consume.

Meat spots are relatively common and should not be a cause for concern. They do not affect the quality, taste, or safety of the egg. You can simply remove the blood spot with a spoon or knife before cooking or consuming the egg.
