RAF cooks getting help making chicken (6)
I believe the answer is:
afraid
'chicken' is the definition.
(thesaurus)
'raf cooks getting help' is the wordplay.
'cooks' indicates an anagram.
'getting' is a charade indicator (letters next to each other).
'help' becomes 'aid' ('aid' can be a synonym of 'help').
'raf' anagrammed gives 'afr'.
'afr'+'aid'='AFRAID'
'making' acts as a link.
(Other definitions for afraid that I've seen before include "Filled with concern" , "Fearful and timid" , "cowardly" , "Filled with fear" , "Timorous" .)
