Wild bird laying in hen's nest

If they are fairy eggs, wouldn't they be yolkless? Would cracking one to see the contents give hints? My girls haven't laid yet so this just a guess.

Usually, but not always. The one I got was but they can occasionally be otherwise typical eggs, just small

Not all fairy eggs, but most are.
Here's one I got 5 years ago.
Size of a quarter withe a dime sized yolk.

Wow, I am quite surprised. Maybe need to send some more pics of the shed where the chickens are shut in every night to keep them safe. During the day, the door is open so they can free-range and lay their eggs in there. No way I can keep wild birds out.
