The temp seems to have held steady throughout the whole process. And I'm glad of that since this is the first experience I've had with an incubator (Janoel 10). I put in a separate thermo/humidity just to make sure. I'm thinking since this was the first batch of eggs that many/most weren't fertile.
And I know there are better, professional grade incubators available but I figured I'd start with this one. Seemed to have pretty good reviews on Amazon and have to say that the temp did stay steady though I did have to wrap a small towel around the outside if the AC was on in the house. But that was only a fluctuation of a few tenths of a degree. Generally I stayed between 99.5 and 99.8 which as I understand it is fine for a forced air incubator.
I'll know more after I hatch out the second batch. I'll probably start that up around Wednesday I'm thinking.
