Cook's co-worker, having space, stuffs fish and turkey the wrong way (6,5)

'cook's co-worker having space stuffs fish' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'turkey the wrong way' is the wordplay.
I cannot really understand how this works, but
'turkey' could be 'dud' (synonyms) and 'dud' is located in the answer.
'way' could be 'r' (abbreviation for right) and 'r' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'and' acts as a link.

Can you help me to learn more?
