An owl statue will get them after it so place one in an area that is open, crows will attack it then you do what you do best after you hit a few they will leave and never return.
I have used owl decoys before and run a line from the base of the mount, to each ear. Then I atttach a small sharp trebble hook to the end of each line, just above each ear. When a crow comes in and gets snagged up, all "heck" brakes loose and the rest of the crows think that one of their buddies is in a real fight. There have been times when I cannot shoot fast enough. After a time, they may fly away and you think they are gone. I then give a distressed call and back they come for more. .....
Whether hunting alone or with buddies, crow shooting is great fun. ....
Be Safe !!!
