Incubator indigestion

Ugh, worring about that incubator. I know I shouldn't. I have done everything save buy that digital thermostat hubby keeps recommending. I have two jars of water in there, the heat sits at 99.5 for an hour before it dips down about 5 degrees and then thermostat pops on. It is warmer way longer than it is cooler. Humidity is a bit high (70) but the 3rd vent hole fixed that. I put a nerf dart behind the thermostat to help the thermostat recognize temp fluctuation. I even made a chart to keep track of turning the eggs! But that fluctuation is giving me indigestion. ugh. At least that's what I tell myself, the incubator is on the way to the kitchen and I like to grab a snak as i press my nose up against the glass. I'm probably going to gain more weight!! ugh..

 

Oh boy oh boy oh boy! jus1jack wrote me back on his thermostat modification..He told me after looking at how the inside of my setup is to move the thermostat closer to the heat source..Seems like those hot water thermostats like a drastic heat change and register it better. I did drill the holes in it's housing. I moved the thermostat above the light and had to watch it, recalibrate, and voila! It is staying within .5 degrees! According to the cheap thermometer/hydrogemeter anyway. So my tummy is better. I am chalking it up to as the hen is settling down to brood and moving around a lot on the eggs. They hopefully will never know the difference and pop out of their shells none the worse..
