Consumed all the eggs initially (3)
I believe the answer is:
ate
'consumed' is the definition.
(to eat is to consume food)
'all the eggs initially' is the wordplay.
'initially' indicates taking the first letters.
The first letters of 'all the eggs' is 'ATE'.
(Other definitions for ate that I've seen before include "Bolted" , "Greek goddess of mischief" , "included in one's diet" , "Worried" , "Ingested" .)
