I hatch mine without the turners for that reason. These and duck eggs (if I don't just steal them from a broody duck right before they are ready to hatch) seem to hatch better if I manually turn them which allows them to cool down some. These seem to be very sensitive to high humidity also so watch that depending upon what part of CA you are hatching in. I know Southern will have the opposite problem of trying to keep humidity high enough.Nice!
Mine has the cool down cycle and the humidity pump. I incubate for the first 18 days in it and then set them up in one of my Genesis 1588 incubators for hatching.
The cool down cycle really helps them develop well.
