We have several species of hawks here, and both large and bantam chickens. Over the years we've had an occasional bird taken, usually a young bantam. I do have a safe run for the birds, and lock them in for a few weeks if a bird is lost. Last year a Coopers Hawk moved in; he sat outside the run for 10 days or so. I kept the birds in lockdown for 8 weeks, and haven't seen him since. I have trees and shrubs and othe cover for the birds, and they are pretty watchful, especially the roosters. Free range is always a risk, but at times lockdown must happen. No hawks are shot here! mary
