Parrot Fertile Eggs
Eggs which have been fertilised, can be incubated and developed into chicks.

If the egg is fertile, then you should see a dark spot around the middle of the egg, with some spider-like veins beginning to form around it. If its not, you should just be able to see the shape of the yellow yolk inside the egg, without any signs of an embryo or veins.
