Day 43 2 Eggs Caving

I am at day 43 on one of my clutches and 2 eggs are starting to cave (slight caving, not too crazy). Is that normal for this time into incubation? I never saw this in my last clutch. Thanks.

Hmm, that seems a little early to dimple. What is your humidity like? Are the eggs in the substrate or are you using egg crate/light diffuser?

Eggs are on vermiculite. I have a probe and hygrometer in the egg container. The probe readings seemed to be off right from the beginning (65%-70%) so I put in the hygrometer and it has been 99% the whole time. The box generates a lot of condensation so I cant believe the eggs are drying out. Temps are 89 using Herpstat.

mine hatched recently at a lower temp and started to cave in around the same time all hatched out around 62 days looking really caved in i wouldnt worry
