Personally, I'd go as normal for the other eggs and not risk them for the sake of one egg. Your odds of getting a good overall hatch are better that way. Lockdown is not an exact science where if you are off a bit one way or the other it means absolute doom. It is actually pretty flexible. There are other things involved in turning and himidity, but to me the main thing is to get then in lockdown before any pip. That lessens your odds of shrink-wrapping some. If you have enough history with your incubator where you have a real good idea when they will pip, you might adjust your lockdown a bit. Mine almost always pip a couple of days early. Some people consistently have theirs pip a day or two late. As said it is not an exact science. I really don't think stopping that one egg a day early and raising the humidity is likely to affect it that much. It is not ideal, of course, but you still have a pretty good chance of it hatching and you are not risking the other eggs.
