Incubation Question

Can anyone tell me if this is normal or what might be the problem? This is my first clutch of eggs and nothing I have read has seemed to address this issue. The clutch looked good and all candled good when laid. After about day 5 in the incubator the shells looked like they were decalcifying; kind of like translucent areas developing and the shells seem to be a bit softer than when they were laid. My incubator temperature is at 89 degrees and I am using moistened vermiculite/perlite mixture for medium….Thanks

humidity is very important . you need to monitor that as well . it needs to be around 90 to 95 % from everything i have read so far . you should have a digital hygrometer set up so you can keep close watch on that as well . as to why the eggs are doing that i'm not sure . i'm not an experienced breeder so not familiar with your problem . i'm sure some of the more experienced breeders here will jump in with help soon though .

Sounds like you're getting condensation on the lid of the incubation container and it's dripping on the eggs.
This will cause translucent patches to form where the shell gets wet. If left uncorrected it can cause you to lose the eggs.

Thanks Clay...Thats kind of what I was thinking. I have removed the cover to see if it clears up. My medium isn't too wet I don't think, it clumps but no water comes out. Any idea what might be causing the condensation, or how to correct it?
