Like sheep are in a shed (7)

I believe the answer is:

sheared

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

'like sheep are in a shed' is the definition.
I can't judge whether this defines the answer.

'are in a shed' is the wordplay.
'in' is an insertion indicator.
'are' going into 'shed' is 'SHEARED'.

Can you help me to learn more?

(Other definitions for sheared that I've seen before include "As sheep perhaps" , "Broke" , "Cut wool off (a sheep)" , "Removed fleece" , "Clipped" .)

I've seen this clue in The Globe and Mail.
