How do you tell the difference between fertilized and unfertilized eggs?

Can you tell if an egg is fertilized after ovulation?

Some women may notice symptoms as early as 5 DPO, although they won’t know for certain that they are pregnant until much later.

How does a hen know if an egg is fertilized?

Can I stop turning eggs on day 17?

Many people find that hand turning every 6 to 8 hours to be the “sweet spot.” If you do not turn the eggs, the tiny embryo can stick to the shell membrane and may die.

The grade is determined by the interior quality of the egg and the appearance and condition of the egg shell. Eggs of any quality grade may differ in weight (size).
