Weirdest thing you ever found in your nesting boxes?

I was just wondering if anyone else ever found strange eggs things in nesting boxes. Just today, I found a sparrow nest made in a nesting box with two chickens eggs and a little tiny sparrow egg. Weird!

That's neat! I have never found any other kind of eggs in with my chicken eggs.
