My eggs have been and stayed at 99% according to the digi hygrometer since day one. They are prob at 100% the thermometer just doesnt go to 3 digits. My temps flux a little from 87.9 - 90.1 but stay at 88.8 most if the time. My eggs started dimpling after 1 week. I even added more water to the vermiculite and put 2 small dishes of water in the egg box. My eggs are on egg crate so not getting saturated and are not getting dripped on either. My eggs have not plumped back up. They do however all have active babies inside. They are at day 29 and the babies when candled are taking up about half the egg. I am starting to think some eggs are just genetically programed to dimple.
