In the past I have run a fan in the incubator to circulate air, but it overheated early in incubation (was hooked to a T-Stat so it just stopped running instead of heating up the entire incubator). That said, I've incubated without the fan before too.

Do you think the color change itself is something to worry about? Should I take the plastic wrap off the bins maybe? And just add like a tub of water to the bottom of the incubator to increase overall humidity so too much doesn't leech out? The condensation on the sides of the tub shouldn't hurt the eggs right?

Thanks so much!
