Can anybody out there let me know what this growth is, growing outside the shell?

A mod will probably move this to the correct thread. It looks like it's just excess calcium from when the hen formed the egg. Completely natural.

That's sure what it looks like to me, too, excess calcium. I've seen quite a few eggs like that.

Happens once in a while. Not every egg that comes off the production line is going to be perfect.
