The humidity has been 99% for a week or so and suddenly dropped to 94% again today for no known reason (it's with press-n-seal and I never even opened the incubator since then), and I see further dimpling in my eggs now. I still see the water level in the perlite. I literally have no idea why the humidity has dropped again. Does anyone have any clue?
(changed the thread title because I still have questions...)
