Young chicks can store prodigious amounts of fat. Juvenile (pre-volant) mutton 
birds often out-
weight their parents. Visually they can appear twice the size (although a lot 
of that might be fluff).

Caged birds can also become grossly over-weight if fed a poor diet and unable 
to exercise. I've 
seen budgies with over-hanging beer-guts (or would that be a 'seed-gut'?).
