Lemon on the chick that died. When you say "correct position" do you mean large end up in the turner and did you place them in a egg carton to hatch and still pipped the wrong end? I'm just trying to understand.
In my cabinet bator I incubated with a smaller tub of water than the one I put in for hatching. When I put the larger tub in and moved the eggs to the bottom the temp started rising so I had to keep lowering it and keep an eye on it until it stabilized. I assume the higher humidity raised the temp. I don't understand or know how humidity and temp work together.

I know it
feels a helluva lot hotter when the humidity is high.
