I swear, I have never felt so stupid about something in my whole life!! I have another question.I think I know the answer, but I'm not sure. We have a standard cochin that has been setting for a while. This is her first clutch, and she is an early-this-year chick herself. She had hatched 4 chicks, and left the nest (without the chicks!) So we took the other 4 eggs that she had and put them in the bator. One was no good, seemed llike it died around day 14ish. One was pipped, and one peeping. The other one didn't have any activity, and is pretty large. I was thinking it might be a double yoker, because of the size of it. When I tried candling, I couldn't really see anything except the air sac. The air sac was moving around? Like when I would 'roll' the egg, on it's side, on the light, the air sac would be on the side closest to the light, all the time. It is not supposed to do this, right? So this egg is no good or what?
