I got that from To Kill A Mockingbird with Dill and Boo, both of them being described with “duckfluff hair”.. What exactly does that look like? I didn’t see any weird characteristics of the characters’ hair in the movie so I still don’t understand what Lee meant when she said duck fluff.
it is referring to the downy that covers a young, baby duck. which is very soft and fluffy!

It means that their hair looks and/or feels very soft and fluffy.
