Nah, that's why I asked if you were using a broody-- the egg should be fine. In an incubator, those eggs dry out FAST. But for some reason, under a broody, they do better and taking a quick peek probably wouldn't do anything... I've done it. BUT-- I must say, I did it on accident, because I was checking to see if the egg was still alive and I picked it up just like that, with a pip in it. I would never do that on purpose! LOL!!! Go check on them!!! And don't forget your camera!!!!!
ETA-- however, when I did it, I did go rub the egg down with a warm wet paper towel because I was so worried I messed it up. But it hatched fine.
