Hi All I have a Brinsea mini ECO manual turn incubator and a Janoel 24 autoturn incubator. Both are fan incubators. The humidity in each is sitting between 42% and 45% in each one. I understand that the ideal humidity is 50% up to day 18 and 55%-65% during hatch. The water channels/containers are full in each. How do I increase the humidity in these incubators?
