Thanks for the response! I agree that it's not obvious the reservoir possibilities.

I don't agree that we're selecting against birds that get infected in the first place, or at least I don't think that's how it works. My understanding is that if any birds on a farm get sick, the whole house is killed. Maybe the whole farm.

To me that seems like selecting for lucky birds not selecting for populations that never get sick because lots of populations never get exposed.

I could be wrong on my understanding or how I interpret the impact, though, so I'm super open to learning more.
