A duck has a right to be feathered! (3)
I believe the answer is:
oar
'a duck has a right to be feathered' is the definition.
I can't tell whether this defines the answer.
'a duck has a right to be' is the wordplay.
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'has' means one lot of letters go next to another.
'a right' becomes 'R' (common abbreviation).
'to be' indicates anagramming the letters.
'a'+'o'+'r'='aor'
'aor' anagrammed gives 'OAR'.
Can you help me to learn more?
(Other definitions for oar that I've seen before include "Rower's implement" , "propels floating craft" , "that may be feathered?" , "Rowing device" , "Propelling pole" .)
