leo eggs - 1st time

[choriona]

This is my first time with leopard gecko eggs and I'm not doing so good. The eggs seem to cave in within an hour or so of my female laying. Does she maybe need more calcium in her diet? She has a lay box with vermiculite and moss (moist) and the eggs are transferred directly to the incubater soon after that is reading at 85-90% humidity and 83-89 F, depending on if the lid is fully shut or not. Any answers to my problem, or general suggestions are welcomed.
