I posted a question earlier in the season because of my second clutch (first ones died unfortunately), ALL of the pink was to the side, or down. When I moved them to the incubator I could see them clearly but I didnt know how long they had been there as they had begun to harden. As such I just incubated them in the same position I found them. As it happens, they have all got wriggly little bubbas in them, so I guess with that clutch it didn't matter. The babies are all in the BOTTOM of the eggs. Correction: I candled a few that had begun to dimple and they now seem to be at the top of the egg, or then again could just be filling more of it than before.
The NEXT clutch were more transparent, and still are. These ones were solid when I dug them up, and pink blotches were all over the shop. Again I placed them as I found them and all contain still contain live wriggly kids (last time I checked anyway).
The third lot, I was there to see them laid. I placed them pink side up, and took extra care with the one that dropped off a rock to land with a thud in the sand. All fifteen were fertile, one went mouldy when water dripped on it, but foot powder soerted that. Mouldy began to wrinkle up last week, and has not responded to extra moisture. I havent put too much in there because the others are all still plump. Nonetheless he is still alive in there.
I read somewhere that the pink side up ensures a stronger blood flow around the egg to the foetus, the weight of the contents can suppress the blood flow if pink side down. Apparently this is often the cause of fatalities later on in the incubation stage when the weight causes the blood flow to dwindle out as the egg gets bigger. I can understand the logic in that, but didnt read it til well after all fifteen were laid. I also read in the same article that once the egg is laid it absorbs oxygen, which makes its way to the top of the egg. If the egg is turned once the air has settled into a bubble, then by turning it you drown the egg, although I dont quite understand that when there is no foetus as such when the egg is first laid.
I think I have that article bookmarked at home on the laptop, so I'll post it if I can later.

why would she not place them all the same way? In nature would some of her eggs not hatch because they are placed differently? I tend to think they would.
