Last time I promise-Quail struggling to hatch?

[Green Bean Quail]

One egg i didn’t see before is hatching! However, it’s been 24 hours (currently 7 pm here) and the baby still isn’t out. The rest pipped, zipped and were out in like two to three hours! Should I leave it overnight? Or try to help?

I'm sorry I didn't see this sooner.
