I have a Little Giant Still Air Incubator that I am using for the first time. Right now I am on day 14 with some Eastern Turkey eggs. The bottom of the incubator has 1 water ring and 2 water canals. Currently I have all of them filled with water and I do not have something to test the humidity with. Anybody know what I need to get to test that??? What should the humidity read right now? During hatch? I also don't know if I need to have all the water canals and ring filled right now. I know the humidity has to be higher when the poults are hatching. Anybody that can help me out please do! Thank You!!!
