County for male deer (5)
I believe the answer is:
bucks
This clue is a double definition.
'county' is the first definition.
(I've seen this before)
'male deer' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for bucks that I've seen before include "County to northwest of London (abbrev.)" , "County (abbreviation)" , "Animals; a county (abbr.)" , "Dollars" , "overseas money" .)
