I googled "crow superstition" and this was the first website to come up...i think it may help you
www.shades-of-night.com...
Edit - the website only tells of superstitions about crows....not how it originated.

I knew a woman that had one as a pet and it was extremely protective of her and recognized
friend as well as foe and acted accordingly.
