Sounds like your neighbors are trying to do the right thing. Too bad they didn't try to do the right thing by their dog before it killed your girls. The dog may actually be a very sweet dog - as far as people are concerned. It will likely make some family a lovely pet - as long as the dog is kept in a securely fenced yard.
We lost our whole flock of 60 hens several years ago - to a neighbor's two collie pups. They were such sweet natured, people friendly dogs, but they killed all of my hens within two hours (I was at the grocery store and the hens were in their pen - the dogs broke down the gate). Turns out they were also chasing cattle. The neighbors got rid of the dogs - took them to the pound. They offered to pay for my hens, but I was just so heartsick (and they were low income) that I just had them clean up the mess. I thought about getting more hens, but I just couldn't bring myself to do it until recently.
