I am not sure what you mean about "glow:. This could mean glow in the dark, or it could mean "candling", a process where they check an egg to see if it has a growing chick inside by holding the egg up to a light source (they used to use a candle for this, now it is done over a lighted conveyor belt). They only way to make the egg glow in the dark is to paint it with glow in the dark paint (won't be able to eat the egg after due the toxic nature of the paint), insert phosphorus into the raw egg (not very practical or edible), or insert a glow stick into the egg. For the last one, you will need to remove the raw egg from the shell first, then insert the glow stick.
For a link on removing the raw egg from the shell, see below.
