I once went to the farm to pick up my milk. They have blue healers and often are training a new puppy/teenager. In addition to the cattle, they have free ranging chickens.
Anyhow, one day when I arrived, there was one of the "teenagers" leashed up near the milk house. On a collar tied to her neck was a dead chicken. Strange, I thought, as I had no education on such matters, but I did figure it out pretty quick.
When I asked the farmer to be sure I had interpreted correctly, he said, yes...that's how we teach them not to do that again. If they are aggressive toward the chickens, they get a thorough shaming, and then the chicken hung from their collar somehow. Not sure for how long, but they stay tied to a relatively traveled area and I think they get the "shaming" a few times.
He thought that it worked for his dogs but I'm skeptical..... It was definitely an education for me to see that!!!
Though I have no experience of my own.
Wow, I have heard of that too. Never seen it tho! That's the exact reason I decided against the breed for an LGD though. The name is derived from how they nip at the cattle's heels, and do have some prey drive. My sweet donkey is showing good promise as a guardian so I have decided against a dog for now. She races at the owl whenever it swoops at my ducks! I love giant dog breeds but they just aren't safe around my parents.
