When you went to clean the coop of the dead chickens...... did you take pictures? So the owner can get a good idea of what really happened to their bird. That plastic wire is fine for keeping chickens in - does nothing to keep animals out. They really need to upgrade to hardware cloth. even regular chicken wire is weak and really only keeps the birds in. Myself - I take pictures of everything so i can reference it later. Maybe is the guy who built the coop and run had to clean up a bad mess like that.... he would be more willing to spend the extra money for the right materials.
By helping them understand what has happended and how they can stop it from happening again, you can rest easy that you have done what you could do. On the other hand.... they are out of town, If you got time and the materials, just go fix it up for them. After all you took the time to clean up the coop. why not go the extra step and make it safe for them too?
I do realize thats a lot to do, but it is one option.
Just my $.02
