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

How do you tell if an egg is fertile with a flashlight?

For those of you who do not share the hatching addiction: “candling” is the method used to determine whether incubated eggs are fertile or not.

What does a blood ring in an egg mean?

A blood ring inside your egg means that the egg was fertile and began to develop, but then died early in the incubation cycle. The blood that was contained in the embryonic vessels leaks out to form a ring just under the shell.

Do chickens poop and lay eggs from the same hole?

When the process is complete, the shell gland at the bottom end of the oviduct pushes the egg into the cloaca, a chamber just inside the vent where the reproductive and excretory tracts meet — which means, yes, a chicken lays eggs and poops out of the same opening.
