Duck eggs over papers (5)
I believe the answer is:
avoid
'duck' is the definition.
(duck can mean to avoid)
'eggs over papers' is the wordplay.
'eggs' becomes 'ova' (term for egg cells).
'over' says the letters should be written in reverse.
'papers' becomes 'ID' (short for identification papers).
'ova' backwards is 'avo'.
'avo'+'id'='AVOID'
(Other definitions for avoid that I've seen before include "Shun, dodge" , "invalidate" , "Sidestep" , "Keep out of the way of" , "Keep away from (someone/something)" .)
