Hubby and I made our "Binki-bator" (as named by our son) today and we're just trying to work out the kinks. I have a temp variance 3 degrees from one side of the bator to the other. I do have a fan in my bator. I also have a water wiggler right in the middle of my egg platform (screen). Should I not worry about the 3 degree variance if I can get my wiggler to stay constant? Also my humidity jumps down a lot when I open the bator for a few seconds (no egg turner here) but it does climb back up pretty good. Is this okay. Also I can only get it to about 46% OR it will jump up to 67% and rising. Any ideas? Thanks all! Looking forward to my first test hatch.
