honestly, i think your temperature is just to low. 99.5 degrees farenheit is the minimum temperature an embryo can successfully develop at. And thats internal temperature of the egg, not the ambient temperature. If the ambient temperature was only 98-99.5, chances are the internal temperature was probably a tad lower. I have found that 100.5 egg level temperature is a happy medium for my high hatch rate.
