I don't think the last egg will hatch. It was half the size of all the other eggs. I managed to check it and although it feels heavy there is no cracks or sign that it is trying to hatch.
I checked the last egg very carefully and I was right it was not fertile, but 9 out of 10 eggs hatched. These were her very first eggs and very first hatch so I would say that is pretty good for a first timer.
