I am not going to freak out. Everything is okay. The chicks I candled are still alive. It is going to be okay.
Okay! So the air cells are kinda small. Well, maybe not. According to the three pencil line drawing they are day 14. According the the "humidity too high, just right, too low" they are fine.
Am I missing something, or are those drawing different?
Regardless, I am far enough along that I upped the humidity.
