Sorry to hear that. In the future or if you have any other issues with eggs going bad/dying, you can use waxed dental floss to "cut" through the egg and remove it from the rest of the clutch. Some people just leave them, mold and all and apparently don't have any issues as a result. Me, I wouldn't risk that, but each to their own. Good luck and hope that helps or someone with more knowledge than I chimes in.
