Gee Matthew, I'm sorry to hear that. I've had mine pretty close to that temp too. I've decided to crank mine up and try to keep it more towards 85 the last couple of days, (and am planning on keeping it that high if/when my girl double clutches here which it looks like she's going to and she's a known doubler). Like it's really going to make a difference now! Ha ha. I sure hope your little normal is okay too.
Have you thought about maybe trying to candle them again sometime? I've gotten pretty crazily obsessed with my first eggs ever here and only on day 56. I actually sat down last night (while watching humidity and temp, of course) and candled all of mine. Out of my ten, nine have moving babies inside. Mind you, this took a lot of sitting and staring and waiting and watching. I've lost it, I think (my mind, that is); but at least now I know. Just an idea if you're still going crazy like I'm quickly becoming already!!
