It's possible it's alive, but doubtful.
Chicks only have so much air in the sack before they MUST pip the shell to be able to breath. By day 23, if your temp, humidity and day calculations are correct, more than likely it is doa. I would suggest opening the egg - in the same manner I mentioned above - just in case it's still alive and seeing what happened.
Maybe it quit developing. Maybe it died because it couldn't get out. It's good to know why sometimes. And sometimes, they just die. I had 2 perfectly developed blue part silkies that died in shell. One pipped internally and the other didn't pip at all. No reason why, they just didn't get out.
