Poulets de Cajun, I think about your awful experience sooo often! I feel so badly for you! If my upcoming hatch fails, it will be largely due to my own errors stabilizing temps, but your technical failure on the home stretch just sucks.
TeresaAnn, I am on Day 18, too, and dealing with humidity and temp. My temp went down only one degree when I spiked humidity. I turned the knob a barely meausurable amount, and it seems to be evened out. My day's plans are to hover over it obsessively.
Let me know how your hatching goes, since we're "due" the same day!
Laura
