How much longer does this one?

My last chick I think is about to hatch I knew hers was a little younger but I want the hen to leave if something is wrong. If anyone could tell me thank you so much. Sorry about the blurry images it was super dark.

That egg your holding looks like it never developed. 3/4 of that egg should look dark with the air sack being clearly visible.

It looks darker than the image is showing when I looked at it there was a huge black dot and some very dark figures my family member could not hold it straight. How much longer should I wait just in case

It doesn't look developed anymore to me. I would chuck it
