I'd be happy to let mine sit without the auto-turner on if I was certain it would have no ill effect on my eggs purchased/gathered locally. With what aveca is saying, perhaps letting them sit for one day would not even be worth it. But letting eggs that are not shipped, leaving them without rotating for a week sounds scary!
On another note- do you guys document or keep notes on your hatches and what happens during them? What all do you consider worth logging? i'm only on a second hatch but I want to make sure I write down enough to find out what I need to learn from. I didn't write anything down for my first batch. I think I was so excited to hatch eggs I wasn't even thinking that some of it might be useful info to look back over.
