jmdtk: Wow. I had no idea that NZ had few predators. I like that country now a lot more!
Seems to work to feed them. If the cat's belly is full, it probably won't eat your chicks. Did you talk to the neighbor?
Aero: I haven't tried them. I've wondered if they would work--rats being prey also.
I'm going to build a chicken tractor and see if I can just remove the birds. I think that might be my best bet. My coop is now seven years old, built of mostly plywood, and it isn't pretty like it was--all chewed up from the rats. So I think it is time to try something else. I think they will stay out of the chickens if they can't find them!
