Question - how do you tell the differance between a gosling and a
duckling at day old with out knowing the farther and mother

For the most common species, mallard ducklings and Canada goose goslings,
ducklings are only about 3" long when hatched, with fluffy yellow down.
Goslings are nearly twice as big, with coarser, slightly gray down. Other
species of ducks/geese are somewhat similar.
