Yes, most people have the opposite problem, trying to bring the humidity up. When I could not find any real info, even scouring the threads on this forum, on how to bring it down, I came up with the "toasted" sponges after much trial and error. I swear by it now, but as with anything there are many factors involved. I just took it on as a science experiment, you should see my notes!

My family thought I had lost it, as I was not going to give up until I could figure it out. I actually do not have that much experience incubating eggs. I just found the variables I could manipulate and went from there. There are so many other factors that we as the incubators have no control over, like egg quality, egg age, parent birds nutrition and genetics and of course that intangible "nature" that we have no control over whatsoever. Never mind the most frustrating factor of all, how the eggs are handled under shipment.
So, we can feel sad when the eggs do not hatch, but we should not beat ourselves up over it. I did everything by the book with this last hatch and still had a very poor hatch rate. It is a roll of the dice in many ways and with shipped eggs we should be thrilled if ANY hatch!
