An article came out today about the discovery of bird flu in ducks in france. http://www.reuters.com/article/us-health-birdflu-france-idUSKBN13N17J I have young ducklings and I am short on resources. Can anyone recommend the easiest/most affordable way to immunize ducks? I believe it is administered by spray? Is that available online or from a vet? Or do you have to actually bring your flock in to get immunized? any advice would be appreciated.
