I am so sorry for your loss! That is horrifying. It happened to my neighbor. The neighborhood dogs hit him all last summer. He actually shot 2 on his property on different nights when he heard them out there. They finally got all of his birds, it looked like a bloody battlefield in his coops! They have never gotten into mine and I am not sure why. I have my runs covered but anything can be broken into by a pack of dogs.
I hope your neighbor makes good on their word.
