Thanks for that tip!
He is trying so hard to pop himself out of there right now.
Maybe by morning! Looks like there are only a couple of tiny veins at the back of the shell yet. Don't think he's considered shrink wrapped considering I can get a cotton swab between him and the inner membrane. May have a couple sticky spots yet, though.
Pretty sure it's a Pekin/GreyRunner mix.
I am sure I will be up every couple hours checking on him again. I've got my fingers crossed!
The next egg due to hatch is tapping on the shell, no chirping yet, though.
A question about that, if it's internally pipped but not chirping, does that mean he isn't breathing yet, and therefore not yet using up the oxygen in the air cell?
