At present, none of my birds free range. I'd like to get them to free range though. My adult dog doesn't bother the birds. She looks at them. Gets close to them. But otherwise ignores them. The 5 puppies though, are a lot more interested. Once I get my pups to accept the birds as family members, it's the neigbhorhood dogs I'd be worried about.... until we get our backyard fenced. There are cats, too - my cats don't give my birds any attention (but birds are in the pen). I've taken one cat into the pen and he just wanted to lay in my lap. Neighborhood cats won't come around with the dogs out. Dogs are not always out, though. Not sure how things will work when we get the birds moved to the farm. I'd like them to free range. In fact, I think all the ducks will ... hope to get started on the floating duck house sooner than later.
