If they are really hunching up spewing green slime and dying like adenovirus nothing "cures" a virus but having had them drop from perches and die within 5 hours spoke to an avian specialist Vet in the states and he recommended 5 days of baytril and a heavy duty probiotic and vitamins. The baytril prevented andy secondary bacterial infection and the probiotic replaced the bad bacteria with good anf the multi vits give the system a shot 5 days and the birds went from close to death to flying half an hour. Dont like medicating but it worked . Darn hard to watch your YBs hunch and die within 5 hours also santised drinkers and scrubbed loft with solution of bleach
