We had our first pip early this morning (6ish) and it's now almost 12 hours later. It managed to make the hole bigger and I could hear cheeping, but it never turned and zipped. I pulled off the loose piece of shell and I can see its beak (which is chirping loudly) but although I see it trying to squirm and move it doesn't seem able to move anywhere. Does shrinkwrapping refer to the tougher outer membrane, or the inner one with blood vessels? If it's the inner than might that be the problem? I've seen mama standing over the eggs all day (not sitting) but it's 110 here so I thought that might be why. Time to help? What do I do?
