It is my first year too and I am using hatchrite. I kept noticing one dimple here and there so I added a tiny bit more water. I ended up losing three eggs, I'm guessing because it was some how too wet. There really can't be any other reason. It's really frustrating and I'm really sad![]()
If you want to do it the easy way, go substrateless. You don't have to worry about how dry or how wet the substrate is. Leave it and go. I switched to substrateless after I lost the 3rd egg on day 27ish. I'm on day 45 now and the eggs I have left are all perfect. I would have lost at least 1 or 2 more by now at the rate I was going. I didn't lose my first egg till day 18. IMO substrateless is the way to go. Hatchrite is supposed to be for first timers and infallible, but I didn't have luck with it.
Oh yeah, and no holes in the hatchbox. You will lose moisture. That' why you use glad wrap/plastic wrap under the lid, to help hold in the moisture. All you have to do is open the lid every now and again for air exchange.
