Dear Puzzled of Wamboin
If they can feed themselves are they Dependent on their parents?  If so for what?
Perahps you are using "DY" as shorthand for "BYEINSNH" or Bird Young Enough that Its Nest was Somehere NearHere?   In that case I recall that in ACT Bird Atlas (which defines 'dependent' as 'fed by parents') days ability to fly was used as an operational boundary of breeding activity.  Of course having seen ducklings walk for 500m and being well clear of the nest hollow before they started, a semanticist could look rather closely at the second 'N'.
Best regards

But ... I do not recall having ever seen a duck feeding its young.

So how do we differentiate DY ducks from their next stage of development, when they are no longer DY so should not be reported as breeding records?
