Home for hatchlings (4)
I believe the answer is:
nest
'home for hatchlings' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nest that I've seen before include "'Birds in their little . . . . agree'" , "Bird's house" , "Something found in Chinese soup" , "See 21" , "10 [HOUSE]" .)
