That's very kind and thoughtful of you. I have spent a few years collecting my birds, growing them out and such. Their bill from me would be much more than the cost of just a replacement hatchery chick. Figure loss of eggs plus chicks I could otherwise be selling for all those months it takes to get my flock back to its' original status. But $ and new birds don't make up for the emotional toll it takes on you. That's great that they offered. But like you say they will have their hands full with the dog and such. Sounds like they MIGHT realize this is a serious situation and take measures to not have it happen again at least on their part. But that won't stop other dogs from possibly approaching. So I think you are right to look into solutions. I love my neighbors. Sometimes things happen that are accidental and that's a lot different than someone who practices negligence on a regular basis! My dogs are fenced... but we have storms and people lose fences, it happens.
Sounds like YOU are a good and caring neighbor! Who doesn't think only of yourself. Wish more people would consider others once in a while. It's nice to meet you and thank you for sharing your challenge that we might all learn something from it.
