What is wrong with this egg?

[4season]

Got an odd egg today


This egg came from a Rhode Island Red that has been laying X-Large eggs for several months. It is not fertilized. Is something wrong with my chicken or is this just a rare but normal occurrence?

Very odd. Would love to hear if anyone else has gotten one of those.

Sometimes an egg gets an incomplete calcium coating while passing through the shell gland, the end of a long 24 hour process to create an egg. I have a five-year old EE who has problems in her shell gland and she sometimes produces eggs with a pin hole in the end like the one you've shown us. Most of the rest of the time, her eggs have calcium deposits at the end, resembling bumps and pimples.

If it happens a lot, it's an indication your hen may not be properly absorbing calcium.
