Beatty of "Reds" (6)
I believe the answer is:
warren
'beatty of reds' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for warren that I've seen before include "densely populated area" , "Area of rabbit burrows" , "Network of tunnels created by rabbits" , "Rabbit home" , "Network of interconnecting rabbit burrows" .)
