Cloverleaf - Thanks. Well, at least the stress is off, and now I can just forget about my old incubator. I just can't wait until I use this new one though! But I don't have eggs coming until the 26th. . . . I'm impatient already.
Days 1-18 I only fill the very inside, L-shaped one, it brings me up to about 50%, and then I refill when I hit around 27-ish. Then during lockdown I fill them all and sometimes (if it's cold and my heat is on alot) add sponges to hit 70-73%, and it spikes into the upper 70s when they start pipping.
