Internal pipping question

[Knighstar679]

Once a chick pierces the membrane for the internal pip does it stay there or can it back out and move back into the cell?

I too would like to know. Good question.

They only have limited room to move around in there. Usually once they internally pip they will breath oxygen until the oxygen starts running out. The lack of oxygen and increase in carbon dioxide will cause spasms in their neck which make them break the shell (externally pip). Then they keep working on that pip, while absorbing the yolk and veins and then zip by rotating and breaking the shell all the way around. As for your question, once the membrane in broken I don’t think they can really get back under it. But I suppose they can move around a little bit in the air cell.

Thank you for your response. I am currently watching for an internal pip on some eggs and wasn’t sure if they had broken through yet.

The egg will feel lighter once they internally pip and you will see shadows moving inside the air cell.
