Never had a hawk attack. I only have silkies and they all free range every day. I keep lots of bird feeders. The wild birds help the most, especially crows and blue jays. I live on 3 acres of mostly wooded land too. We do have hawks around but I have many hiding spots like under porches, decks, bushes, etc. The silkies mainly stay right around the house and coop. The wild birds at my feeders are worth their weight in gold. They tip off the chickens. Also have chicken protecting dogs.
