How you can you tell if a chicken egg is fertilized or not, and will a hen automatically sit on it to hatch?
Answer
If the egg is held up to a light bulb or other light source, the embryo will show up through the shell. This is called “candling.” A hen will sit on a egg, whether or not it is fertilized.
