Still air incubator - I just took the egg turner out, added more warm water, and checked the temp. It was a little low, so I waited a while thinking the water might have needed to come up to temp a bit more. It's now been almost an hour and the temp is very low. With the egg turner in there, the thermometer was reading 99 (I have it set low because I know by my previous early hatches that the thermometer runs high). Now the thermometer says only 85! I turned up the heat but am afraid to go to bed in case it gets too high. Any suggestions?
