I am thinking about getting the Octagon Eco 20 incubator, but it comes in both manual, and automatic turning. The difference in price is like 50-70 dollars though, and I'd really like to do this as cost effectively as I can. My problem with a manual turner is that since I work 12 hour evening shifts, this means on the days I work, I get home and go to bed right away. I might be able to turn the eggs once before I go to sleep, then turn them once just before I go to work 8 hours later when I wake up. They would be unattended pretty much on a schedule of 6:30pm to 8 am. Then left unattended from 9am to about 5:30pm. Will they still hatch if I am only able to turn them 2 times every 24 hours?
