Coward has to manage the hen-pen (7-3)

I believe the answer is:

chicken-run

I'm a little stuck... Click here to teach me more about this clue!

'pen' is the definition.
(chicken run is a kind of pen)

'coward has to manage' is the wordplay.
'coward' becomes 'chicken' (similar in meaning).
'has' is a charade indicator (letters next to each other).
'to manage' becomes 'run' (both can mean to organise).
'chicken'+'run'='CHICKEN-RUN'

'the hen' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?
