This is my first hatch and I go on lockdown tomorrow at 11am. I have a still air little giant. My humidty gage is kinda wierd. i calabrated it and it is 11% off. The problem is all it will say is low. It dosn't give me a number. When I add water it will say 21 or 22% for like a min and then it goes to low. My question is should i assume my humidity is 33%? When i go on lockdown i am going to add a sponge under one of the vent holes so i can wet it to help. Also am i suppost to remove the other red vent plug tomorrow? That is what the book that came with my bator says, will that help or hurt my humity???
