Ugh, I have been having some horrible hatch rates for the last few months, was doing well in the spring (averaging about 75%, even with shipped eggs). Now, I'm lucky if even one egg hatches (poor lonely blue cochin). Recently went back to the incubator I started with this spring, temperature is set where it was this spring, a hair under 100, bumped the humidity up a little as I am hatching bantams (per one of the people that sent me eggs) to 50 - 60% and they still seem to be dropping like flies? Disinfected it with alcohol before this last set. What else should I be trying?
