Broodiness

I like where they left him joining the Daily Planet though and wanted to see that journey continue but they made him a side character his own sequel and doubled down on the broodiness.

Broodiness Under natural conditions, most birds lay only until a clutch is complete, and they will then incubate all the eggs.

To stimulate broodiness, an owner may place many artificial eggs in the nest, or to stop it they may place the hen in an elevated cage with an open wire floor.
