I live in a suburb with a small yard that I would like to let my chickens free range in. I know that there are some Red Shouldered Hawks in the area, and possibly screech owls, and haven't let them out unless I was outside with them. Is there a time of day that hawks don't hunt? Since I live in an area with lots of houses and small yards that are fenced in would the hawks even bother to hunt here? If so is there anything I can do to deter them?
