I have a sinking feeling I ruined my whole hatch. I set up my hatcher today and stole the therm out of the bator, replaced it with an older therm. Come back to find it reading at 105! So I stuck the original therm back in the bator and watched it tick up too. Here's the thing: when i set the eggs I put the therm at the bottom, when i moved the therm to the top it started reading high. Does 2 inches of space really make that much difference? I had put the therm on the screen on the bottom because it is oval shaped and doesn't lie flat on the eggs. Doomed?
do you know for a fact that your therm is accurate ?
do you have a fan in your bator ?
how long was it at 105 F ?
give us a few details if you want answers..
