Chicken caught bird (6)
I believe the answer is:
craven
'chicken' is the definition.
(both can mean cowardly)
'caught bird' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'bird' becomes 'raven' (raven is a kind of bird).
'c'+'raven'='CRAVEN'
(Other definitions for craven that I've seen before include "Chicken" , "Cowardly - Yorkshire area" , "Cowardly, abjectly afraid" , "Yellow" , "Chicken-hearted" .)
