Wow that's crazy! I bought a still air. Follow the directions to a "T" and I might get one chick. I figured out that I can't plug the vent holes like the directions say to do or they all die. I have all the trays filled and wet rags in there and they can't get out of their shells. They can tear a small hole in the membrane but that's it. If I don't pip the egg and help them out they die. im going to compare humidity vs dry see what happens. They are wet so it could be too much humidity.
