Not A Sign Of Fertilization
A blood spot does not mean an egg was fertilized. It forms when a blood vessel on the yolk ruptures while the egg is being made inside the hen.
Why It Actually Forms
The vessel breaks on the yolk surface during formation of the egg, or in a similar accident in the wall of the oviduct on the way out.
Chemically And Nutritionally Fine
Eggs with a blood spot are chemically and nutritionally fine to eat, cooked or not. The spot does not change anything else about the egg.
Simple To Lift Out
If the spot bothers you, scoop it out with the tip of a clean knife before you cook. Nothing else about the egg needs to change.
Why Shop Eggs Rarely Show It
Mass candling machines catch most blood spot eggs before they reach a shop shelf, though even scanners cannot catch every single one.
A little red fleck never means a bad egg. Fresh Yolk still checks every batch before it reaches your Multan morning table.
