Is this egg fertile?

[phoenixxflame]

I know there is a way to tell, but I don't know how.

Nope, not fertile!
Did you cut the yolk to see?

You can tell if an egg is fertile because there will be a bulls eye in the middle.

Next time, check BEFORE you crack it. Go somewhere dark and shine a bright flashlight through it to see if there's an embryo. Doesn't look fertile to me though.

When I cut the yolk, what will it look like when it is fertile and when it is not.

The egg was laid about an hour before I cracked it, so an embryo in it isn't possible. Lol

Well, I assume you'll see an embryo!

This is a very good description of embryonic development. The life cycle of an embryo | BackYard Chickens

For lack of a better term (my ignorance), the yolk is similar to a placenta. It feeds the embryo while in the egg and for up to 3 days after hatch. The embryo is not inside the yolk. They are attached to one another. If you cut the yolk of a newly laid egg it will look like this:

p.s. I believe most of this information is interchangeable for ducks and chickens besides the length of incubation and other things I am ignorant of.
