I also free range mine but only when we are home and can listen outside or are outside doing whatever. I have 1 acre and my chickens have learned the sound of my basement door opening and will usually come running from that sound. If they are too far away to hear the door i just call chick chick chickens and then they all come flying at me
haha.
I dont have a fence and they havent gone to my neighbors property. Also, i do worry about predators with hawks, coyotes, fishers and once i saw an eagle!
I dont have any problems with dogs but a 4-H friend of mine had 10 bantam hens killed by a Rodesian ridgeback dog before her father was able to chase it out with a shovel.
