Okey dokey then, I have a Hova-Bator 1588 (forced air) First hatch I had a 30% hatch rate. Didn't candle or have Hygrometer. Think I might have had around a 50% rate had I had a hygrometer as it apeared several of the chicks in eggs dried out after pipping or zipping. 14 days into second incubation, candled at day 7 took out the definate infertiles (only three but there may have been more), three thermometers agree temp steady at 100.8, bought a hygrometer it says 65% with the water in tray C as according to instructions. So the the question is; on the sticky at the top here it says Humidity should be 58-60% during incubation and at 65% for hatch . . . is this solid fact? Or does everyones vary a bit? Is mine to high? I WANT THESE BABIES!!!!
