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.
