Hen's hatchlings (5)
I believe the answer is:
brood
'hen's hatchlings' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for brood that I've seen before include "Ponder mournfully" , "Worry over" , "Clutch" , "Think resentfully about family of children?" , "Think anxiously for some time" .)
