Thanks for your thoughts. I’m in VA, definitely not high altitude! It has been very hot. Miss the days when I was younger and upper 90s was something to talk about. I live in an old home that does not have central air/AC. Last year I caved and got a one room unit that sits on the floor. The incubator is in this room and I don’t have an option of other locations. It is in the opposite diagonal corner as the AC unit. Also I have had the incubator covered with old towels the whole time. I did take out a spare thermo/hygrometer and put it outside of the bator - it’s been reading about 60%. So yes, drying air, but not very dry (which means it’s way worse outside, yuck!).Location has a lot to do with humidity problems in the incubator. For example, If you are in Texas or the Southeastern United States, the a/c is probably running. That dries the room out, but the problem is solvable by turning up the thermostat a bit and running the a/c a bit less.
So I went to work today -only half day! - and came home to fine one chick had somehow squeezed itself past the wire mesh wall divider and was sitting over top the water wells right under the bulbs. Totally could have drowned or burned!! And the one mosaic egg that was piped appears to have been pecked raw through the pip!! chick is still alive in egg, and appears to be on the end of the wing covering its face. It was also tipped over and knocked around despite having egg cups. I chipped a little bit away from the pip so I could see, then let it be to finish it’s own hatch. Suffice it to say the four that hatched during the day yesterday are evicted!!!
