Treat with Tylan or gallimycian until all symptoms have cleared. Vaccinate all birds on property with vaccine. Medicate all birds for another week, then revaccinate in2- 3 weeks. Any bird left showing symptoms would be a carrier and would need to be delt with. Continue vaccinating your birds every year.
