I'm facing the same problem . My auto pump needs to be forced to operate to increase humidity . It isn't automatically doing so when the humidity drops below the set 45% . How did you eventually overcome this .
Angelobutter , did you face the same problem or did your pump maintain a steady set humidity and automatically run when humidity dropped ?
I had too many issues with sticky chicks and humidity and wrong end popping.
I'm sticking with my cheapy styro bator that never gives me a problem
