The first is patently untrue.Everyone passes NPIP. Because it's not pass or fail, it's just sign up to be monitored.
Just curious, what does AI have to do with chicken testers ignoring ducks?
NPIP is a POULTRY program, not exclusively a chicken program. Ducks are a known reservior for AI in the wild - the disease isn't nearly as fatal (or even debilitating) to them as it can be for chickens. I had hoped that the State of Florida, where I live, and whopprovides free testing to NPIP participants, would also test the ducks in my combined free range flock for AI. Rather disappointingly, the inspector chose not to do so.
Having said that, if my ducks were carriers for HPAI, I 'd have lost many or most of the chickens shortly thereafter. High mortality is a defining trait of HPAI. Since I've lost neither chickens nor ducks to disease the last two years, its clear in retrospect that they weren't.
I've not investigated what I need to do to get my ducks included in my NPIP registration - but the F'rs are so hard to catch free ranging, I'm not strongly motivated to do so. I'm also not under a major migratory flyway, so my risks are lower than many.
