I know an LG Still Air can have differences in temps throughout the bator, but apparently humidity can be quite different as well. The front of my bator tends to run hotter than the back, so naturally those eggs are hatching first.. started yesterday.. day 20. The dial I have reading the humidity is at the back which reads between 65-70%. But apparently it isn't that high at the front of the bator, because so far all 5 that pipped have gotten stuck because the membrane dried. Didn't really realize it until after the first one died in shell after pipping. Assisted the other 4 and they are all doing well. I put the front plug back in with a bit more water at the front hoping that helps. Just an observation I thought I'd share for those using a still air.
