They are free range, so other predators could get them. I have never had an issue with any other day predator, just his dogs. I have already told myself that as much as I love to watch my birds free range, if I lose another bird to a predator in the day, they will not be allowed the freedom they have now.Sounds like electric fencing might be a good investment for you. Even though the dogs have been rehomed, other predators could get in the same way.
