Egg Found in the Wild
Observe the egg you found for a few days. Assess if there is any activity such as birds traveling back and forth to the nest. This could be a sign the egg is being nurtured and therefore still alive.
Touch the egg gently with the back of your hand when you find it. If an egg is alive, it will feel warm. If it has just fallen from a nest, it may have been warmed by a bird, yet still be dead. Therefore, you will need to perform additional checks to help clarify if it is alive.
Inspect the shell of the egg. It should not have any cracks or flaws in it if the egg is still alive. Look for thin, hairline fractures or other distinguishing marks that could show that it has been damaged and is no longer alive.
Egg Found Near an Incubator
Check the eggshell for damage. Large cracks or small areas of webbed cracking could indicate it has been knocked and broken. It should have a smooth, unmarked shell if it is still alive.
Shine a bright flashlight through the egg in a dark room, and look closely at the inside. If the egg is alive you will see veins running through it. The process of removing dead or rotten eggs during incubation that uses this method is called candling.
Compare the color of the yolk with a regular infertile egg by candling each egg separately. If the egg is still alive, the yolk will be pale and not as orange as the infertile egg.
Watch the egg as it is incubated. Identify signs of life such as slight wobbles when the animal inside is moving around.
