My Buff Orpington laid this one yesterday. She often lays "oddly" textured ones but this is the weirdest by far.
Lemmy see if i can find some pic i took a few years ago. Gonna edit this comment in a minute.
Here ya go. This was laid by a fully grown chicken that usually laid completely normal eggs.
Comparing against my hand this thing was something like 3.5cm long.
