If you did free ranging there would be some lost to predators, it happens. However, if you can even let them out for short times, you would see how happy they are. Life is always a trade off, complete safety and no freedom or complete freedom and no safety. Most of us that free range try to find a mid point we can live with. My DW and I sit with our birds every evening. We feed table scraps or scratch while we have a beverage and watch them. Someone on another thread was mentioning watching free range chickens is as calming as watching the waves in an ocean. I have to agree. I do not feed my birds until evening,(bedtime) then they rush back into the fence and coop then. To me giving in to predators is like giving into terrorist, I refuse to do it, Live free or die!!!
