I have a clutch of 4 eggs in the incubator, and it's on day 21. On about day 10 I noticed a very slight dimpling in the egg sitting on top, which is progressively getting a little worse. I was told to leave the eggs together unless I knew that they had just been laid within the past few hours. So I left them all together. Well, because I did that, on egg really isn't in contact with the vermiculite, and I think it is a little dryer than the rest. The humidity is about 80-85% and i don't know how to get it any higher. I'm wondering if I can mix up just a little more vermiculite and set it on top of the eggs surrounding it so that it touches the egg that seems to be deflating. I don't see why that would be a problem but I just figured I'd check before I do it. Any other ideas to raise humidity?
