I have a Hovabator 1602n still air. I am currently on my second attempt with nine eggs. I had temp holding steady at a 101.2 (for over a day) when I added the eggs. It immediately dropped the temp down to 99.3. After a few hours temp then climbed to 101.8. I have been making micro adjustments but can not keep it in the range 101. It either drops into the 99's or goes up to 101.8. Is this too high of a temp? As for a fan. I was thinking. I have a air pump for a fish tank and wouldn't you know it, the tubing fits perfectly into one of the vent holes on top. On my next attempt/batch, would this provide enough air circulation to be considered has having a fan? Does a pc fan added to still air kick on and off or does it run steady?
