That may well be. I'd welcome suggestions for something better. The link in your original post seems to no longer be valid. I'd love a recommendation for something with an automatic turner, good airflow (this says it has airflow but it wasn't strong if it was there), and a reliable hygrometer. I'm assuming they're sold somewhere, but it's also conceivable there aren't reasonable incubators available for sale.
Are the digital thermometers you're mentioning things that sit inside the incubator? I think I'd need a far larger incubator to get them in near the eggs, and the way the turner worked in this one I think it might be a challenge even with small thermometers. I've gotten a couple USB-connectable thermometers but I'd have no way with this design to get them into the enclosure. I'd welcome advice. But ideally I'd like to find an incubator with these functions self-contained and reliable.
It was saying 60% up until we locked down, and then we moved to 70%, assuming the hygrometer wasn't completely confused. Are you saying it was too low based on symptoms? The display said we were on the mark, but I don't trust it.
We didn't wash them but they didn't look soiled. We'll wash the next batch.
Thank you. It was all quite sad.
