If there are no other eggs waiting to hatch, you should get that humidity lowered. They only need the humidity while they are hatching so membranes don't dry on them. High humidity is not good (or necessary) for them after hatching. The humidity will also make it take longer for him to dry and fluff up. Maybe you could put him on a towel inside the incubator so he's on a nice dry surface, and that will also block some of that humidity from getting up to him from below. If you have vents you can open in the incubator you can try that as well to get him more air (but not too much that the temperature drops of course).
