Condensation at any percentage is a sure sign (in my book) that you have sufficent humidity regardless of instramental readings. I'll have to research that possibility though. Logically I can see where that would cause a difference. But, if that is an end product of still air then the question would arise: Does a still air incubator need less humidity at lock down to equal the same expectations of a forced air?
My first hatch I bought a brand new thermometer for my borrowed bator and I didn't check it-cause it was brand new- after my hatch pretty much bombed and I had to very late hatchers, one that survived and one that didn't, I bought three new thermometers and checked them to find the original thermometer was 6 degrees off...which explained my late almost non existant hatch. I have an LG fan forced, atm, older model. I am hoping to be able to get a new bator before I hatch again. This one just has too many hot/cool spots.
I know mine does. Under the heating element runs close to 2 degrees warmer than in the center of the bator and the corners run warmer. It wouldn't be bad if you were doing a smaller amount of eggs and could place them strictly around the outer edges and keep that at recommended temp and let the center be cooler, but when you have more than that area covered you have eggs in multiple temp ranges and rotating 30+ eggs on a regular basis is a pain right in the buttocks.
I'd suspect that your average temperature may have been lower than you thought it was. Leave them in the incubator.
