The little owl. Oh dear, what kind of egg is that?

Curious little owl: What is hiding in the big egg?
The little owl calls out: "Oh my, there's an egg in the neighbor's nest!" Where did it come from? And what should be done? The rabbit, the bear, and the butterflies have all sorts of ideas, but only the sparrow knows: you have to keep the egg warm. And, crack – it happens: A little chick hatches out. Hooray!
