I have been incubating a very important batch of eggs in my Sportsman incubator. I cannot seem to get a good hatch in it, so I am going to use another incubator to hatch out of. I have a forced-air Little Giant and a Still-Air Little Giant. The forced air, I have never been able to get ANYTHING to hatch out of. The still-air has had good hatches but I am concerned that they are coming from a fanned environment and going into one with no air circulation. Then there's the issue of the still air will hold the temperature and humidity very well but when the eggs start to hatch, the temperature in the incubator drops, as much as 5 degrees yesterday. Which would you use? The still air or the forced air and please tell me why!
