Like female not looking very well (5)
I believe the answer is:
ashen
'not looking very well' is the definition.
(I've seen this in another clue)
'like female' is the wordplay.
'like' becomes 'as'.
'female' becomes 'hen' (female chicken).
'as'+'hen'='ASHEN'
(Other definitions for ashen that I've seen before include "Bloodless" , "showing signs of anaemia" , "Anaemic looking" , "Wan, pale" , "Pale (with shock/illness)" .)
