2013 I had horrid hatches, with everything. Humidity was too high, from what I read.
2014 I started dry incubating. I only added water when the digital readout said it was in the 20's. (I have a thermometer/hydrometer, that measures humidity in the room, OR put the probe into the hole in the top of the bator... I have the Brinsea Oct. 20) The humidity in the room was about 50-65%.
So... maybe added water, filling the reservoirs once or twice. (with turkeys too). Then at lockdown, raised the humidity with sponges in the reservoirs and felt on the 'floor', dipping into the 'wells'. Readout on hydrometer was about 70%. Of the fertile eggs left in the bator after candling, I had 85-90% hatch rate. ONLY one or two pipped and dead in shell compared to almost half in 2013.
