I had two hatch on day 20. Since then I have had no movement or anything from the rest. I can't really see in them. I did the water test. Where if they sink or float and according to that they are viable however they are supposed to move. And none of mine did. There isn't any movement or chirps. Should I call it? Also is there such thing as too much humidity at the end? I have a still air incubator.
