[SBB] Canada Goose - What's wrong with this picture?

Title: Canada Goose - What's wrong with this picture?

Took the following photograph in Alviso on May 1st.

Two (presumably) adult Canada Geese with chicks. 1 chick visible at bottom of the picture

If so, why the big difference in size in the two “adult” birds?

Is this a pair? Is there sexual dimorphism in this species? Are these different subspecies?

If not a pair, is the smaller, slender bird an immature from an ealier year/brood?

Or just a perfectly normal variation, nothing strange here?

Don’t know if its relevant but the smaller / slender bird appeared to a bare patch of the forehead as seen here:

A sick bird?

Thanks!
