Chewy sweet in most of feedbags (6)
I believe the answer is:
toffee
'chewy sweet' is the definition.
(I've seen this before)
'in most of feedbags' is the wordplay.
'in' says the answer is hidden in the clue.
'TOFFEE' can be found hidden inside 'most of feedbags'.
(Other definitions for toffee that I've seen before include "Sticky sweet" , "Hard-to-chew sweet" , "Chewy confectionery" , "sticky stuff" , "can we not do something for it?" .)
