You'd probably need to start with a lone crow. As a group they can be quite nefarious and clever about it. I once slowed down a group of crows from killing and eating an injured bird; once they boldly got past my interference, they formed a sub-group and that sub-group followed me all the way home (1/2 mile) hopping from tree to tree, cawing the whole way.

A subgroup of crows is called a manslaughter

I saw crows doing that with a fox once. The fox looked very displeased

No wonder people thought they were witch familiars.
