I haven't looked at the information lately, but it's my understanding that a lot of birds just simply carry it without being affected, and problems come and go with others. I wonder if it's one of those microorganisms that are always in the body, and only become a problem when something throws the balance out of whack.
That's what I'm saying. But from what I read, they do get affected eventually, but until they do, it can easily spread if another bird comes into contact with something from the carrier.
