Hello, we just lost a silkie to a hawk. I'm confused on how to prevent this since the chickens saw the hawk coming and ran into their coop. The hawk just eyed them for a moment then flew into the coop and picked up the smallest silkie and flew off. He actually dropped the silkie after he flew off but it was too late and the damage was done. How would I prevent this in the future? It looks like the chickens hid in the coop and did everything they could have to prevent the attack. Is overhead netting the only thing i can do?
