Here are some articles to read about vaccination of chickens, and you will probably find the information you are looking for there: http://www.merckmanuals.com/vet/pou..._poultry/vaccination_programs_in_poultry.html http://www.the-chicken-chick.com/2012/03/answers-from-chicken-vet-on.html http://edis.ifas.ufl.edu/ps030 http://www.jefferspet.com/products/newcastle-bronch-vacc?sku=F7J6&gclid=CL7nw77Q4cICFW4F7Aodz1IAtg
