Free ranging does have its risks. I free range, and it's a risk I'm willing to take. Yes, there is always the chance of loss to a predator, but I think my chickens are happier when they can be out exploring, and scratching and pecking and doing other chickeny things. I also have a secure coop and run for them to be locked in at night, when family comes to visit and they bring their dogs, or if I suspect a predator is lurking about. If your chickens are beloved pets and you're concerned, I would suggest not free ranging. At least not the way we do it. We let them out in the morning, go about our day, and lock them up at night. When I do it, I count heads to make sure everyone made it in. When DH does it, he just shuts the gate. Some people let their chickens out only when they can be in the backyard with them. Ours have acres to wander if they want. We live on a farm, and the coop is quite a distance from the house. I don't have time to sit and watch my chickens all day.
