So pigs can possibly behave like old hens! (6)

I believe the answer is:

gossip

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

'behave like old hens' is the definition.
I can't tell whether this definition defines the answer.

'so pigs can' is the wordplay.
'can' indicates an anagram (I've seen 'canned' mean this (canned can mean drunk)).
'so'+'pigs'='sopigs'
'sopigs' with letters rearranged gives 'GOSSIP'.

'possibly' is the link.

Can you help me to learn more?

(Other definitions for gossip that I've seen before include "Idle, malicious, chatter" , "Schmooze" , "creating scandal" , "Hearsay" , "Scandalmonger" .)

I've seen this clue in the Evening Standard.
