Secondary colibacillosis due to primary viral respiratory infection generally sets in about 10 days after primary viral infection and once you see the symptoms at post-mortem, treatment can only be with antibiotic, but recovery may not be 100% as severity in each bird varies. Doing a sensitivity test on culture can better allow the selection of an effective antibiotic. Meanwhile if possible add vit B12 in water to stimulate intake.
Using vaccines to control IB is a better solution for future flocks.
