I have 6 EE hens who free range in the back yard all day. When I first got them a few months ago, I really appreciated the crows in my neighborhood because they kept the hawks away. But I've began noticing that the crows are now scaring my chickens away from their food and water sources and eating it all. And when I feed the chickens snacks I have to stand out there like a living scarecrow until they're done eating. There's also two blue jays who drive them crazy. They're not even afraid of me like the crows are. One blue jay lands on the grass to distract the chickens (they love chasing small birds) as the other one grabs the food that they've abandoned. Then they take turns. It's frustrating to watch. Poor chickens. Would adding a rooster to my flock help keep them away at all? Or maybe a fake owl? BB gun? Thank you!
