I may be way off here but I was wondering if there were ways to encourage crows to hang around. I have a large flock (gang, I think) of them that wander around over the 4 or 5 farms around me. When they are around, they give the hawks all kinds of grief - . I've never seen that they have any interest what so ever in my chickens. So I was wondering if there were any ways to encourage them to spend a little more time in my area. Sorta like feral, flying guard dogs.
