The temperature in the incubator seems to fluctuate a lot. Too cold, the embryos won't grow, too hot and they will die. We are fine tuning the temperature by turning the dial on the incubator. We turn the dial ever so slightly to increase or decrease the temperature. Having a thermostat would make things much easier.
Turn, Turn, Turn. We turn the eggs 3 times a day so that the embryo doesn't get stuck on one side of the egg shell. We are careful to wash our hands before touching the eggs. They can pick up bacteria and die.
Waiting. It's hard to wait and wonder if anything is growing in the eggs.
