Provide minimum 100 sq ft per goose

Solution

Allocate at least 100 square feet (approx 10 sq meters) of outdoor space per goose as a bare minimum.

Explanation

This minimum allows for some movement, but extensive foraging won't be possible, and the ground may become bare quickly. This is more suitable if their diet is heavily supplemented.

Notes

More space is always better. This minimum assumes regular cleaning and supplemental feeding.
