I put my very first eggs in the bator. I am a big chicken so I only put two in there. I have never done this before, and I have a still air bator. I t has no humidity ready only temp reading. It has stayed steady for 24 hours now. I figured I could do all the reading and asking questions until I turn blue in the face, so I might as well give it a try and see what happens. I don't even know if my eggs are fertile or even viable because I had them sitting on the counter in a bowl for 2 days. I also figured that a hen leaves her eggs in the nest for a time before sitting on them. We will see. If something starts stinking then I know I didn't do it right. That's why I only used two eggs.
