I've been hatching chickens for several years in a home made incubator. Learned a lot along the way. I just got an auto turner and a store bought incubator (hovabator) and this is my first time setting eggs in the auto turner. I'm mid day 5, and even though these eggs are darker than the ones I have incubated before, I thought that since I could see something by day 4 candling on other hatches I'd have a quick peek.

The yolk seems to settle on the bottom and the darker part (I'm guessing the embryo, these are Marans eggs) goes to the bottom too. I can't actually see any veining yet. I'm not sure if that is normal with a turner, or if the chalaza(umbilical) might have been damaged. All of the eggs I've set and turned by hand the yolk floats and the embryo, slowly floats to the top.

other information: I went and picked these eggs up myself from the breeder, it was a 4 hour car drive after I got them. I have the air cell end up in the turner. temperature has been pretty consistent though one side is a degree hotter than the other. (on one side 99.0 - 99.3, and the other 99.8 - 100.0 I have 2 trusted thermometers inside the incubator) the incubator thermostat says it is 100.0
 
Oh missed this entirely sorry. I had 6/12 hatch the embryo sinking turned out to be entirely due to the auto turner. I set a few more eggs i could see through clearly and they did the same thing and still developed.
I had the opposite experience when I went from an upright turner to a horizontal turner, the yolk seemed to 'stick' on one side....had good hatches tho.
