I have done a bit of herding with my rottweilers. The ranch we went to had a number of rottweilers. The dogs, when not working, were secured. The place had a huge quanity of chickens and ducks roming around. They would get into the dog area. The older rottweilers/other dogs were trained not to bother the fowl. When the new dogs came into contact with the birds, a few were killed. The owner had to train the new dogs to not kill the birds.
I had to train my dog to not go after the chickens too. He was titled in herding ducks, geese and sheep. But he would want to try to get a chicken if left to his own devices. Eventually he learned to ignore the chickens in the barnyard.
I actually think that the only dogs that would herd until the stock dropped dead would be poorly or untrained dogs. A dog that is trained to just an HT level is still poorly trained. The ranch owner's main stock dog was routinely left in the sheep barn, with the sheep. My own dog has been left in a 250x350 foot pen with 10 sheep and he didn't run the sheep while the ranch owner dealt with something else for 10 minutes.
A good herding dog is all about control of the stock, not moving the stock. Putting stock in a corner and keeping them there is a popular thing. Herding trials is about controlled movement of stock, not running stock.
Give your dog a job to do. Let the dog know that the chickens and ducks are YOURS and not to be touched by him. Rotts are smart dogs. But if you haven't taught him that the birds are not to be touched, how is he to know that? He probably thought he found a great game to play! A rottweiler's mind is a terrible thing to waste. You are wasting the best time to fill it with good training by leaving him alone to his own amusement.
If you want to blame something for the death of your animals, look in the mirror. The humans in your house are the ones responsible for the deaths of those chickens and goats. Not the dog. The dog was doing what untrained dogs do. If you don't want dead chickens and goats, then get off your butt and do something about it. You bought the dog, now do something with your dog other then setting him up to fail.
