I believe Stress, and poor poultry husbandry has a lot to do with it yes. If the birds were not confined in such tight quarters, had better ventilation and better poultry husbandry I think that they may never had that problem. Just think how fast a virus can spread in tight quarters or even in a poorly ventilated house in the winter..
Now I do know that salmonella is a bacteria and not a virus but I believe it to work about the same when you are talking about a tightly confined animal weather it be a Chicken, Dogs, Cats, Swine or Bovine... Now don't get me wrong I do not Free Range all my birds. I do have breeding and laying pens but they are well ventilated houses with adequate pen space and they do have runs attached to there pens.

I find it hard to believe my chickens, your chickens and just about every one on BYC's chickens has not eaten a rodent dropping at some point in time. Animal feed=Rodents.
Why no Salmonella?
Animal feed does = Rodents but it is how you deal with the rodents. I go to extremes to keep rodents out of my barns and pens so rodents are far and few between. But you are right chickens will eat rodent dropping at some point in time and I believe that chickens have a immunity to Salmonell when in small doses and when the bird are healthy.
Its just like with CRD all birds will have it but they will only show sines of it at times of stress or when unhealthy for some other reason.
I would like to add that contaminated feed is only one way that poultry can get salmonella.
Other animals (rats, mice, wild birds) and insects (cockroaches, flies, beetles) can carry salmonella, very good "biosecurity" is a necessity on the farm.
This just my opinion.
