I have a little house in which I live all alone. It has no doors or windows, and if I want to go out I must break through the wall. What am I?

Why this works

This riddle cleverly describes the scenario of a bird developing inside an egg. The "little house" refers to the eggshell, which indeed has no doors or windows—it's a sealed environment protecting the bird. The line about having to "break through the wall" highlights how the chick must crack the eggshell to escape into the outside world, making the answer both literal and metaphorical. The imagery invites us to think creatively about a familiar concept, adding to the riddle’s charm!
