Religious retreat has converted member of the flock (6)
I believe the answer is:
ashram
'religious retreat' is the definition.
(type of religious retreat in Asia)
'has converted member of the flock' is the wordplay.
'converted' indicates an anagram.
'member of the flock' becomes 'ram' (male sheep).
'has' is an anagram of 'ash'.
'ash'+'ram'='ASHRAM'
(Other definitions for ashram that I've seen before include "Indian hermitage" , "Indian religious retreat" , "spiritual centre?" , "Place for religious retreat (in India)" , "Place of religious retreat for Hindus" .)
