I had a similar issue when I was away and my wife messed up the perilite to water ratio, I came back and my eggs started to deflate around 30 days or so. I placed a wet paper towel over them for a few days and it fixed the issue. After this mess I started using a light diffuser in my tubs and wet the heck out of the perilite. I have no air holes, arrange eggs to not touch the sides of the tub and press and seal tub before covering. Congrats on the clutch, always a nice bonus to buy a female that drops eggs.
