King keeping almost new poultry farm (7)
I believe the answer is:
hennery
'poultry farm' is the definition.
(I've seen this before)
'king keeping almost new' is the wordplay.
'king' becomes 'henry' (I've seen this before).
'keeping' indicates putting letters inside (some letters kept inside).
'almost' means to remove the last letter (almost the whole word is kept).
'new' with its final letter taken off is 'ne'.
'henry' going around 'ne' is 'HENNERY'.
(Other definitions for hennery that I've seen before include "Run" , "Poultry farm" .)
