I'm coming up on day 6 (at 1pm) and so far my temperature and humidity have been super stable, until that is this morning, woke up and the fire had went out in the night, inside the house the temp is 65, temp was 98.9 in the incubator and the humidity was around 40, mind you this is lower than my Hova Bator recommends and lower then my first batch... For the last 6 days the temp in the house never got below 72 and I haven't had to adjust the dial on the bator at all, it has stayed between 100-101.3 and the humidity has stayed between 45-50 if it drops below 39 I have added about 1/4 cup of water and waited for it to stabilize (usually an hour) and then wouldn't have to touch it for another two days. I had heard inside temps effect the incubator but until today didn't realize how much.. I'm not worried, it wasn't a drastic drop, got a fire going and warming up the house, but thought for anyone new to incubating this info might be useful.
