Controlled and guided herd of cows, maybe (5)
I believe the answer is:
drove
'herd of cows maybe' is the definition.
(drove can mean a group of animals)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for drove that I've seen before include "kicked hard" , "Moving flock; forced" , "Herd of cattle" , "Moving crowd" , "acted like Mr Toad" .)
