I think no issue, the egg happened to be " wind eggs, cock eggs, fart eggs, and fairy eggs". Got possibilities the bird to lay the egg without the yolk.

NO YOLK

These weird eggs have some equally weird names — they’re also called wind eggs, cock eggs, fart eggs, and fairy eggs. Wind eggs can happen in mature hens but often occur in pullets.
