Hi!
Welcome to BYC. I wouldn't free range my chickens for this reason. Build a large enough run for them to be free but safe. Really, unless you are going to shoot every woodland creature, you will always have predators. I am in the camp of securing the chickens rather than killing all the animals. We have an imbalance in our eco system right now in my area, so I'm having to deal with this too this year. And it is definitely illegal to shoot some of our predators. So, we are working on ways to secure our chickens, while maintaining their very large run. (App 4000 SF for 9 chickens).
