I would say their was just something wrong with that egg I have never seen then laid dimpeled in like they were dry abit.But i have seen them with a part of the shell concaved alittle and when they get close they do cave in allot like you said .
I think if you added just alittle bit more water ,not much and ounce or so sould do. Is there air holes in your tubes ? If you add alittle water by the time it starts to work ,it will be about the time they start to dimpel . It would take about a week for them to pop bake up. I would add alittle water to it with out getting any on the eggs. This is a nice clutch of balls the father was a Y.B. Thet were close to 3 weeks here
