According to the FAQ on the DC-Forums the dead egg stays on your scroll for two weeks:

"' Q: How do I know if my egg is dead and if it is, how do I get rid of it? A: A dead egg is denoted by the egg graphic being broken in half horizontally. If you wait 2 weeks, it will disappear from your scroll on its own. There is no way to get rid of it besides waiting. '"
