Fellow artist initially idly drew ducks and crow (4-1-6-3)
I believe the answer is:
cock-a-doodle-doo
'crow' is the definition.
(thesaurus)
'fellow artist initially idly drew ducks' is the wordplay.
I cannot really see how this works, but
'fellow' could be 'ed' (I've seen this in other clues) and 'ed' is present in the answer.
'ducks' could be 'oo' (duck means zero in cricket) and 'oo' is present in the answer.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for cock-a-doodle-doo that I've seen before include "Early morning farmyard cry" , "Farmyard crow" .)
