First time incubating eggs. Need advice

So this is the first time I’ve ever bred my snakes. And so far I have 4 healthy eggs in my incubator, but they have been getting kinda rinkly despite the fact that my acurite says it’s 99% humidity it’s only been a week since they have been laided. Not sure how to post a picture on here. I’m new to the site

I seen many people use press and seal to help keep moisture in their tubs Justin Kobylka use it with much success, also Gavin from Balls2You has a whole series on hatching healthy babes on YouTube best wishes always 😊

What kind of incubator are you using? And how are the eggs situated? I've always used moist vermiculite & planted the eggs about 2/3 of the
way in the vermiculite. And yes, covered the container tightly with plastic wrap, then poked several pin holes in the plastic for ventilation. The
moisture should NOT condense on the plastic...if it does, it's too moist & it can drip on & drown the eggs. Eggs that "wrinkle" (cave in) a little
will normally plump back up if the humidity is raised soon enough. Unless they are non-viable...did you candle them?
