Trying to get the temp/humidity right to get ready for my rescue mallard to pip into the air cell. I think it might have gotten too hot at one point but not for very long. Mostly under temperature if anything. 97° F while I was trying to adjust humidity. I put a clean water diffuser in there and that helped with humidity, but the egg movement slowed, so I removed it. It doesn't seem to be moving inside and just won't pip that air cell. Meanwhile, I'm pulling my hair out, worried that I've somehow murdered a duck embryo. A light showing through the air cell (you can only see through the air cell) doesn't show any ruptured blood vessels.
