Hello to all the awesome hatchers I have a "Little Giant" and corresponding egg turner. Most of you recommended the air fan accessory which I am going to purchase and install (although a test run with two thermometers in two different places yielded consistent 99 degree heat for the duration of the test , placed on top of dummy eggs in different corners. (Course; there was no water in the Bator...). Now, we have the matter of humidity. I've looked through a couple dozen different posts and I am SOOOO confused... How do you check humidity, and how do you steady it, keep it consistent, raise or lower it? If you have a fan running inside the bator, does the water evaporate more quickly? How do you add water without continually opening the bator? Also what is a wet bulb thermometer? How do you use it? Where do you get them or how do you make them? What does "lock down mean? I've done a fair amount of reading and can't seem to find the answers anywhere... Anyone? Anyone? I soooo appreciate any help you can offer!
