Floating test..deceivingly named

All the eggs I ever did this with except for 2 have all sunk. Both eggs you see sunk and when I candled them they were alive. The weight vs air cell is why they sink..not death. The ones in the incubator ALL sunk and all are alive ready to hatch. The Water test is the correct term and floating or sinking is irrelevant. You watch for movement period. If no movement then candle. The two eggs did not move in water but you can see the 2nd one i did and candled in video moved when candled. So..don't assume just cuase they sink..the sinking and floating belief is not accurate.
