I had one that hatched on the 14th of this month, I was able to cut the yolk sac off , there was like a tiny string like thing holding it to the intestines, so i cut it there. I read to push them back in with a q-tip, but that was way too big, so i took the cotton off the end of it , soaked it in water, then peeled some of the paper off to make it thin and tiny like a toothpick. got that wet, used another qtip to get the intestines wet , they were really sticky and didnt want to go back in, once wet i was able to easily push them back in , i worked on one side only till i had it all back in. I gave the chick some saveachick , it slept all most for 24 hours, but today i can cant even tell who it was. It was my very first hatch. I only set 8 eggs, 2 werent fertle, the other 6 all hatched on their own and are now all very happy. I searched and searched on here but couldnt find a real answer. I hope you were able to save your chicks.
