If chickens can spread the bird flu amongst the flock (and to humans), why not to wild birds?Any game and fish department.
Even though wild bird carriers of HPAI are often asymptomatic, that doesn't necessarily mean that some aren't getting the virus by being in close proximity to backyard flocks and hatcheries etc where there's contamination. To me, since it's often spread through feces and other bodily fluids, and because chickens poop so much, it doesn't seem far fetched that a wild bird coming into contact with contaminated chicken feces might then become a carrier for the virus.
I'd be interested in a study on this but internet searches haven't turned much up.
