I've been hatching chickens for about 3 months now. Nothing has hatched. Not a single egg has popped. Nothing. I have no idea what I am doing wrong. I have The Little Giant incubator which sets the temperature perfectly (99.5) and turns the eggs for me as well. The humidity, I'm on my own there. I add in a cup of water every two days as I was told by a fellow chicken hatcher. I did all of these steps and still, I have no chicks. What do I need to do? What am I doing wrong? What do you do? Please help!
