We lost a lot of our crow population when west nile virus hit this area. Now we're overrun with magpies
Both are hard on the fruit. The magpies compete with the free range chickens for food. As with all wild birds susceptible to West Nile, I'd be cautious about letting them mingle with your chickens. I understand chickens can contract west nile virus, but not pass it to humans, but I'm not expert on that. Predators are likely far more dangerous than west nile, but it's just a thought.
