help figuring out an malformed egg issue?

[John in Binghamton]

Dear BYC folks:

One of my chickens laid this egg today. Any insight into what could have caused this? The deformity is at the tip. It's a little smaller than usual, and the deformity at the tip is hard calcium--it's not soft. Looks almost like a little swirl on top of the egg. No obvious health problems in the flock or disturbances, and these are layers in their second year with plenty of space.

Nothing wrong with it. People often times have been raised with grocery store eggs where they also get eggs like this, but they are sorted out and sold for business baking. This give the false impression that all eggs are consistently perfect or something is wrong.

Just a little variance in productions, nothing to worry about at all.

Hard to say what exactly caused it, some hiccup in the shell gland.
Could be a one off or could continue.
As long as the bird is eating/drinking/pooping/moving around OK, I'd not worry.
