I have an egg that is positioned upside down. Most of the eggs I have that do this never manage to hatch properly. Some of them manage to make a pip on the lower end of the shell, and if they can do this I can always save them, but many of them never do. Has anyone ever assist hatched an upside down egg successfully? It's so hard because all of the blood vessels are at the bottom, and you can't know where the head is. Any suggestions? This egg is very precious.
