This is a robin.
An egg is considered "dead" if it does not show any signs of development or movement when candled (illuminated with a light source). To determine if an egg is about to hatch, you can listen for peeping or chirping from within the egg, observe the egg rocking or movement, and notice external pipping (cracks appearing on the shell as the chick starts to break through).
