UPDATE
Yesterday we were outside and the neighbors finally came home. The man came over to us, and his girlfirend followed. They never apologized. then the lady nearly accused us of hitting one of their dogs over the head a week or 2 ago. They said they had to take him in for medical treatment. We never touched thier animals!
We still haven't filed charges. I am not sure if we will only because we suspect the guy of being an ex-prisoner, and we aren't sure what he is capable of. My husband is a correctional officer and he recognizes some of the tatoos on this man as prison tattoos. So we are worried about what he may do to us, our kids, or our property. But we may still file charges, especially if the dogs come back.
I did take pics of my dd's scratches and the chicken. We caught the dog carrying the chicken in its mouth, and we know he did it. He seemed very proud of his "catch." But now my dd is scared of bigger dogs, and is really scared of these dogs coming back.
My dh did consider shooting the dog, but since we are in the city he could have been arrested for it. The AC officer told us that if we were in the country, it wouldn't have been an issue because the dog attacked our livestock, but here we can get in trouble.
