I am now on day 20 and think that I may go insane waiting for the eggs to hatch. So if i set them on Fri night, I know that I don't count Fri so should I expect pipping in the morning, evening, or just whenever they decide? I am not going to be home for most of the afternoon/evening will they be okay? Here is my drunk chickie? Is it normal for the chickie to stumble around? why is there a small pile of yolk in the incubator?
