Okay, I'm really excited! The only problems I've ever had with my Mini Advance were humidity related. I've kicked myself for not getting the Mini Advance EX, but it was so much more money I couldn't justify it at the time.
I've been trying to figure out a way to put a hygrometer in the 'bator, but as you know, there really isn't any room if you want the eggs to keep turning.
I think I found a low-cost solution to my worries! I purchased a tiny analog hygrometer from Cigarextras.com through
Amazon for only $10. It's only 1.4" across and is made of metal with a real glass lens. I did the salt test last night and it's within 1%. I took some clear shipping tape and rolled it into a couple of thin tubes, then used it to stick the hygrometer to the clear plastic dome.
Now I'll know when I'm having humidity problems, and as you can see from the dial, it's a little too high for the regular incubation period.
So, that brings about another question -- how do you LOWER the humidity without getting it too low? I have water in half the reservoir as directed, but if I sop it all up, won't the humidity drop too low?
