(KLZA)--The Nebraska Department of Agriculture confirmed another case of bird flu this week.

The latest case was found in a a commercial broiler flock in Johnson County.

This is the state's sixth case detected this year and comes nearly two weeks after two cases were reported in backyard flocks. All but one of the Nebraska cases have been reported this month; the first case of the year was reported in February.

Bird Flu symptoms can include birds that aren’t drinking water, are suffering from in coordination, or lacking energy or appetite; decreased egg production or laying eggs that are soft-shelled or misshapen; or birds with nasal discharge, coughing, sneezing, and diarrhea.

Wild birds can also be susceptible to the virus, but Nebraska officials have previously noted that migratory birds can carry the virus without becoming sick at all.
