don't implicitly trust the temperature and humidity readings on the front of your incubator. I have seen temp readings, especially, be off by a couple of degrees. If yours is reading cooler than it actually is, then that may be part of your issue. The other folks here can shed more light on this. In my previous hatches, every time I had a low hatch rate or deformed chicks, I could always trace it back to something I did not check or the surrounding area going over temperature. Good luck and I hope your future hatches are better....
