Remove the source immediately. Flush the gut with activated charcoal or molasses water (1 cup molasses per gallon, once). Keep the bird warm, quiet, and hydrated. Antitoxin exists but is rarely available for chickens. Mild cases can recover in 1 to 3 days.
Prevention
Remove animal carcasses (mice, dead chicks) from the coop and run. Do not let feed get wet and moldy. Cover ponds and standing water that can host dead aquatic life.
