Yeah I have been doing research and I take extensive notes during my hatches. I think I have a formula now that should work. while it isn't recommended by everything I've read the best approach I had was last hatch on the front of the year I used the flashlight that I use for candling to partially cover one of the ventilation holes and humidity came up. I think when I clean and disinfect this go round I'm going to reseal the bottom. Then I will use the aquarium gravel in the water channels as a heat sink, at lockdown I will plan to add water to the channels and prbly still use the jars with sponges and water. Another variation I tried that seemed positive was adding a airstone and aquarium pump into one of the jars.
Need to do some more reading on the links that Sally just posted. I seem to be making it to lockdown with decent success but haven't been able to consistently get my hatches above 60-70%. More practice and time hopefully I will get there.
Remember there are plenty of chicken nuts here.
