HELP Ducks dying on day 28 I have put safety hole in un pipped egg

[New duck mommy 2021]

I think the little egg with the pin hole in has i live chick in it. im not sure whether i am wishful thinking, im sure i saw something through the tiny pinhole and movement in the egg, again im not sure if you can see movement just under surface of an egg shell with a torch (not candling) just through incubator or if im going mad on hope. Do i recandle the eggs. This one may of internally pipped and has pinhole air hole. the others have nothing??

I would candle again
