I am brand spanking new to incubating. I have NOT had a problem with my temperature but I DO have one with my humidity. I have two hygometers and a thrid on its way. The problem is that the two hygometers I have are reading different levels. When they are low they both read similar but when my secondary hygometer that is place in with the eggs between the auto turner reads within normal levels, the built in hygometer reads low by a 10% varience. What I have read says that the humidity needs to be between 45-50%. Is that correct? Is there a wider margin then that for chicken eggs? If the margin is that small then how does anyone keep it regulated within that parameter without having to sit next to the incubator all day. I have to work 8 hours a day outside of my little farm. Can anyone help me. I tried to regulate it by just adding water to the drip trays. That was MADDENING! So i read where you can add water to a sponge that seems to be working better to at least keep the humidity close to if not in the 45-50% parameter. I guess I just want to know if theres a trick to keeping it within the level when your away and if there is a wider margin for the humidity. At what point will I lose my eggs from the humidity? Is it as critical as the temperature?
