I have never had them die from starvation, I think that would take quite a while. Some just die, for unknown reasons. You have a good timetable with your other one, see how long that one takes to hatch then go from there. If it's obvious that it will not hatch on its own, then try to help it out, but do it slowly. When this has happened to me, and I decide its time to help, I will first just peel the egg shell around the egg - leaving the egg liner and membrane. Then I will leave it for about 12 hours and see if this helps. If nothing is happening, I will then peel away the white egg liner, leaving the membrane - do it real slow as sometimes the membrane will stick to it. If I draw blood, I stop, that tells me its not ready to hatch yet. I will also take a Q-Tip and dab water on the membrane making sure it stays wet and pliable. They have a tendency to dry out or get sticky and you must keep it wet for the duckling to be able to get out. I will leave it again for another 12 hours or so, just dabbing it with water on the Q-Tip. If it still will not come out on it's own, then I will use the Q-Tip to slowly move the membrane over its back, so it can lift it's head, if it wants to, if not I will leave it in that position for a few more hours, before lifting its head out. I do try to always let the duckling come out of the shell by itself, it will if it's ready.
