I am so unhappy and frustrated right now. I didn't touch anything on my incubator (except for opening it to turn eggs). I didn't adjust the thermostat. It's been sitting between 37.2 and 37.8 for days. And today I got up and it was reading 39.8 and those poor eggs were so hot! I left it open for about four minutes to let some of the heat out, adjusted the thermostat, and got it back down to 37.6, but I'm scared to even leave the room. I think the main problem is the cooler is just too thin and flimsy (maybe it's responding to the outside temperature -- we've been having a mini- heat wave here, for December), but I also don't trust the hot water heater thermostats anymore. And I'm terrified I've once again addled my eggs.
Dang it, I was feeling so confident after my first two hatches went off without a hitch! This was an expensive way to discover I am not properly equipped for hatching on any large scale. And I simply don't have the money to buy a real incubator right now. I just don't.
I'm going to go take a look on ebay real quick and see if there's a used one going cheap or something.
