Deposits, as eggs (4)
I believe the answer is:
lays
'deposits as eggs' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lays that I've seen before include "How Pertelote produces" , "Puts down; songs" , "Arranges" , "Sets down the old songs" , "Minstrel's melodies" .)
