My family is just getting into showing chickens at 4H and some small local shows. I have been learning about all of the diseases that can be brought home from shows. I have started vaccinating my chicks for Mareks, Newcastle/Bronchitis, and Laryngo. I am curious to know what diseases everyone vaccinates for? Also, can you vaccinate older hens against Bronchitis if they have not ever been vaccinated? I have heard that this one causes hens to stop laying eggs???
