I have 4 chickens. I got 5 eggs.

I'm almost positive I collected all eggs last night, and I even checked twice this morning and didn't see one hidden in the bedding. But i got an "extra" this afternoon. I only got 3 eggs yesterday, so it's possible one was hidden from yesterday. But it's a small nesting box and not easy to hide eggs and, as I said before, I'd checked TWICE before finding the mysterious 5th eggs (which was in plain view. It's a rollaway box. I can't even get the fake eggs to stay in place throughout the day).

Conclusion? I have magic houdini hens. ????‍????
