The eggs are in her clutches (3)
I believe the answer is:
hen
'the eggs' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for hen that I've seen before include "Female bird" , "Domestic egg layer" , "Domestic fowl" , "Adult female chicken" , "Clucking female" .)
