Another Diamond Dove chick dead in shell, Judy left it and I left her to see if she'd get back on but she didn't, its a couple of days overdue.
I opened it, and the air sac was really big, but not pipped. There was a perfect little chick inside, fully developed but hadn't hatched for some reason.
Its the 3rd time a chick has developed and not hatched so I don't know whats going on with them. They aren't growing too big for the shell, and the shell can't be too thick so I don't really know what has happened :(
