Incubation Question!

[Teal]

Hey yall! I'm brand new here, and I did a search as thoroughly as I could looking for the answer to my question.. but I didn't find anything quite specific enough, so I hope yall don't mind me asking I apologize for the length of this.. I've NEVER dealt with eggs before, so I'm a bit excited and nervous! If you want to skip straight to the question, just scroll to the last paragraph

Exactly a week ago I caught a lovely California Kingsnake. I would estimate her to be about 3.5 feet long.

I brought her home and set her up in one of the many tanks I have. I've kept a few reptiles before (I mostly keep arachnids), so I had all the equipment.

I decided to try to feed her, since she's been here a week... last night I put her into a feeding box (a clear plastic container with moist paper towels), and was going to go get some mice for her today. Why I put her into the feeding box last night, I couldn't tell you! But...

You can imagine my surprise when I woke up and she was nestled around a clutch of eggs!

Had she been in her enclosure, she would have had access to her decent sized water bowl, which I've read they sometimes lay in if there isn't a lay box.. so I am really glad I put her in the feeding box last night!

Anyways, there are 7 eggs stuck together and one apart. I marked the tops of them all, so they wouldn't get rotated (though I only plan on handling them to candle them once or twice in the future). I candled the apart one, even though it looked fine, because I've heard sometimes slugs will get pushed aside.. but the apart one is fertile. I candled a few of the stuck ones as best as I could, but I've never handled snake eggs before so I was being extra gentle. The stuck ones I candled are fertile, as well.

So, in a near state of panic, I watched a LOT of YouTube videos on how to make a homemade incubator. It just so happened I had a styrofoam cooler, so I put a heating pad at the bottom, put a little shelf in, and put the plastic container with eggs on that. For medium, I used dampened coco fiber (I THINK... it comes in a brink and expands in water? It's what I use for substrate for my arachnids). But IMMEDIATELY the eggs started to dimple! So, I went through all my stuff and found a bit of moss that I had used in a shed box for a snake.. so I damped that, and put it over them. Then I put a moist paper towel over that.

My question is - when should I start seeing the eggs plump back up, if the humidity is okay? I don't want to keep adding moistness, only for it to end up being too much... but I really don't want them to dry out, either! The temperament in the little container is 85F. Thanks for any help!
