I hope it goes well for you! Anxious to hear responses. Some are strict about the lockdown, humidity, etc. Some are more laissez faire and will candle at will, knowing the mom gets up and moves sometimes, will sometimes leave the nest for a sip of water, etc. I've only incubated 3 or 4 times now. I do try to leave them alone, but 25 days is on the long side for a hatch time of 21 days. But, the temps were a little low...
My question would be, and maybe someone can answer - what is the risk of leaving them for say 2 more days and NOT candling. I mean, what does that hurt? Surely by 2 more days anything that was going to hatch WOULD hatch. And anything that isn't going to hatch wouldn't have hatched anyway. It's sorta erring on the side of caution. I just know sometimes those pups can explode, but if you don't see any oozing in there (or smell something foul), you are probably good. SO... with that said, unless someone comes up with a reason not to, I think I'd leave them alone and not candle.
BTW, after my first hatch was over, the next time - WAAAAY easier, since I kinda "knew" what to expect. So, breathe deeply and enjoy the experience.

Let us know what happens!
