oH MY!!! He looks just like the one I hatched yesterday...2 days early, yolk sac unabsorbed. Thought he would die. The inner membrane was like a sheet of glue. I had to unstick the shell from his wing after he had full hatched. I too have given sugar water...wet paper towels to keep moisture while the yolk is doing whatever it needs to do. Mine is getting stronger..not walking...sleeping a lot. My fingers are crossed for you and your little ones.
