Around my house there are lots of crows, flying in groups or alone, making loud noises. The chickens don’t like them and once when a group of crows flew by I found all my chickens in corner of the coop. When they are free ranging and a crow pirches on a telephone wire, the rooster warns them. But the real question.. will crows hurt them? And if they do/did, could a chicken defend itself or the others?
