So I’ve seen a lot of zoos with outdoor bird enclosures some even out of cages and roaming around freely but my question is how do these birds not get bird flu? There’s a large bird sanctuary near where I live and they have parrots flying around freely and I’d love to know how they keep the birds safe from bird flu. I own chickens and ducks and in the past I’ve had to cull them because they get bird flu. How to zoos/sanctuaries avoid this?
