Ihave better luck if I leave the lid on the tupperware container. Holds humidity much better. I just drill 4 quarter inch holes around the top. You can move the egg around a bit for at least 24-48 hours without harming it, but no harm in marking the top with a pencil and not turning it.
Early this morning, before 8 o'clock I was out drinking my coffee and "Frogger" was up and digging. Tonight when I got home I scooped out the dirt by hand and found 2 more eggs. The 2 on the right in the photo!
So, they went onto the incubator with the dates and a mark on the top. Life is good.
