I have read a few threads on here about dry incubation and decided to try it. I just did my 7 day candling and my air cells are huge. Like as big as 18 day air cells using the classic picture for air cell measurement. Since this method uses low humidity it stands to reason the air cell will be larger and then it will shrink later when you increase humidity. Right? Wrong? I had 4 that looked infertile so I cracked them open. The membrane was very dry on a couple. My hygrometer says 40-49% pretty much all the time, but it is one of the Styrofoam incubators. I am hatching EE eggs, which have a much thicker shell and are difficult to candle, but could the air cell be different also? Anyhow. Please help.
