Okay, so 10:30 am (PST) and still no pips on 4 and 7. I candled four (not super well, but it was up against the glass so I held my flashlight up to it and could see the air cell) I don't see an internal pip? But I also don't really know what that would look like. The air cell is facing the right direction.
I also candled 7 (this one was even harder to see as it wasn't right pressed up against the glass) but it looks like the air cell is kind of big. It could just be that I'm seeing the wide side of the slant on this one. Should I wait to open the incubator? It is day 21, the other five are fluffy and moving about so I would like to put them in the brooder, but not if it will put the other two at risk.
