I made a new bator from a dorm sized refer and using a 100W bulb and a water bed thermostat was keeping the temps at 99-100 degrees for the last couple of days. Today I decided to put a computer fan behind the light bulb. The temps went up 1.5-2 degrees and I'm still trying to adjust the thermostat back to where it was. I have 2 thermometers inside with one having a remote readout and the other is wired, they are within .5 degree's of each other. I'm going to dry hatch this batch just to see what will happen, I fought with humidity the last time hatching only getting 7 of 14.One of the thermo's inside reads humidity also and it's at 45 so we'll see how it goes.
