Hi, this is my first batch of eggs and i just candled some eggs that came via post office, they we're rough on them. I have 10 ee and a doz marans. The marans we're too dark to see anything, but all the EE have detacted air cells except one that is all dark except for the air cell which doesn't move. Idk if this makes a difference, but it feels solid, like it has heft to it....what does that mean? While i'm at it, the detacted air cell eggs, those go into a carton big end up without moving for a couple of days, right?
