Cloudy egg whites are a sign of fresh eggs.

If sometimes you can’t tell the old and new eggs together, you can put the eggs in a cup of water. If they sink and lie on their sides at the bottom of the cup, it means the eggs are still fresh and edible. But if the eggs slowly float up, it’s the beginning. broken.
2. What is the "thread" on the protein...?
If you see thread-like objects on the egg white, they are actually egg bands, which are used to fix the yolk in the center of the egg white. They are absolutely safe and can be eaten with confidence.
3. Why do egg yolks sometimes have blood streaks?
Egg yolks sometimes have blood streaks/blood spots attached to them. This is because during the yolk formation period, if the hen's ovipositor is damaged or ruptures and bleeds, blood may stick to the egg yolk, making the egg yolk "red" and safe for consumption.
4. Is it normal for the egg yolk to turn green?
When eggs are heated in water, the sulfide in the egg white reacts with the iron in the yolk, causing the contact surface between the egg yolk and the egg white to appear gray-green, which is normal.
