I raise thousands of chickens, pouts, ducklings, goslings and keets every year.
Every year I receive calls from people that need help mending mauled fowl.
We receive calls every month looking to replace hens and flocks that the dog, neighbors dog, stray dog, mother-in-laws dog ate. We keep a big special paddock with our handicap flock which is mostly made up of rescues from mauling.
THERE IS NO DOG THAT IS 100% SAFE WITH FOWL.
Now - before you go off...
I also raise dogs. I have raised Rotts, Blue Heelers and Border Collies. I run sheep, work with sheepdog associations and I show (AKC), course and hunt with Borzoi from a partner's kennel.
ANYTIME A DOG IS ABLE TO MAUL OR KILL A FOWL - IT IS THE HUMAN'S FAULT.
The dog is doing what the dog does. Some breeds are better with fowl then others, some will actively hunt them. Choose your dog carefully, train them well (there are GOOD trainers out there that can teach you to train your dog for 'hands and mouth off') and spend a lot of time with your dog. Teach them to view the flock as their pack - include them as much as possible, desensitize them for noises, peeking, running and flying that fowl does. Even if it goes against your personal beliefs about hunting - call a reputable bird dog organization that uses retrieval of live birds.
I work with several organizations that train their dogs to bring the fowl back uninjured. They spend hundreds of hours developing and training for this. I spend hundreds of hours working with people to keep their flocks safe, not just from raccoons, coyotes and bobcat, but from their dogs. I visit homes, farms and ranches continually. I work with 4-H in 3 counties, animal control in two states, and wildlife management throughout the PNW flyway. All this information and still, once in a while, I will lose a chicken to my blue heeler. There is a price for keeping an apex predator in close proximity with prey.
Enjoy your dogs, enjoy your fowl but never forget that the food chain rules.
