We have 3 dogs.
The Golden retriever is 13 and not much interested in chasing anything. She pretty much ignores the chickens.
The Shorthair Pointer/ Brittany cross is nearly blind and deaf, but he stalks the chickens when he can see them. He is only in the yard when they are out when supervised. The other day he went in their pen, and they took exception to his cleaning up their treat plate and the seven of themn surrounded him. I rescued him before he did anything to them, but he was a little scared and might have retaliated if I hadn't gotten there to extract him. They also tend to peck at a couple of skin tags he has on his legs. All in all a volatile situation.
The young dog (2 1/5 years old) is a long-haired standard dachshund. I'm not sure what to think of Lucky. A couple of days ago, two of the pullets ganged up on him and chest bumped him. He clearly knew he wasn't allowed to fight back. He came back to the door where I was standing and wanted to come back in the house away from those awful dinosaurs. I think that he might take off someone's head if he got pecked or bitten. Supervision only at this point.
Long and short. When the dogs are out and the chickens are out, so am I.
