My entire tiny town is a bird sanctuary. I had let the chickens out to free range and my DD came running in the house saying to come look at the sky. I went out and there are hundreds of ravens circling in the skys above our town. Now TONS of them are roosting in the trees on my street. How worried should I be? Cause I'm freaking out! I have put the chickens back in thier run and left the dogs outside.
