Solid white thing following brittle egg out

[Souch]

So I let them out in the morning, and when she came out she walked 20' and dropped one, quickly, and almost attached there was a solid white thing about the size and length of my pinky finger. When the others saw it, it was a race!! The first one grabed it and ran, and the other one exploded the brittle shell egg, I had already poked at it trying to figure out what the heck. The rest of the flock, a dozen birds, proceeded to chase her all over the yard, acre plus.
Thoughts / Concerns?

Sounds like one of those weird eggs. I wouldn't worry unless it happens again.

Ditto Dat^^^

More info would help, if you really want to figure it out....
Knowing more about......

your flock size(numbers, ages, genders),

your coop(size in feet by feet with pics),

and what and how exactly you are feeding,

might offer clues to if there is a solvable problem.
