I called the manufacturer and the lady was not really of much help. She said "keep playing with it." Hope you can get better information than I did!
I won't ever be volunteering to do this project again! I stayed up till 2am last night babysitting the incubator because it spiked to 103. Took the lid off to let some heat out, then touched it a hair... drops to 97. I mean... a HAIR.
I actually left the temp setting and put towels around it (left vent holes open) and then it cruised up to 100 all night long and stayed there. Just turned eggs this morning and it's climbing back up, hopefully to 100 again, that'd be nice.
The anxiety I feel is horrendous. I mean, I understand they're just eggs, and the 4h people have said it's ok, sometimes they hatch and sometimes they don't but then I have kids being all disappointed, and I hate that. I feel completely responsible for the thing, even though it wasn't my project to begin with!
Grr. Sorry. So tired.
