Could my chicks be dead in the shell at 24 days?

[CallyB57]

My hen Sugar has been sitting on a huge, 3" egg for 23+ days. Today makes 24. I believe there would have been 2 yolks in the egg, and I'm wondering if they could not pip. Should I leave the egg alone, or try to see if they are alive and just can't get out. A couple of days ago I THOUGHT I heard tapping, but not since then. Please give me some advice. Thanks.

Unfortunately they're probably dead by now (assuming this is a chicken egg). You could carefully peel away the shell in case they're still alive.

Its a personal decision to try to help a hatching egg! I watched on youtube a video about helping that was very informational.
