Ron all that information is super interesting. It is a great list of the resources available at the time.
Just a few things that maybe are not completely clear-
1. It would be impossible in a practical sense to differentiate carriers from immune birds. Both would survive exposure. Carrier birds appear normal in every way, but are still infected and can potentially shed virus. Immune birds would those who were exposed, but eliminated the infection. What a huge boon it would be to have a test to differentiate the two.
2. Even if young birds are kept physically separated from adult birds, it would be impractical to prevent transmission of dander around the same farm - it would be carried by the wind, on clothing or shoes, on equipment, and many various ways
