Poultry (7)
(Another definition for pullets that I've seen is " Young hens".)
'poultry' is the definition.
(I know that poultry can be written as fowl)
This is the entire clue.
(Other definitions for fowl that I've seen before include "Bird, maybe domestic" , "eg Chicken" , "Bird to be eaten or hunted as game" , "Any farmyard bird" , "Cock or hen" .)
