MPI to start culling 80,000 hens infected with bird flu

The Ministry for Primary Industries will start culling the 80,000 hens infected with bird flu tomorrow in a process which is expected to take up to three days. The jump in infected chickens comes after it was found the highly pathogenic H7N6 strain had spread to a second shed on a free-range egg farm near Moeraki in Otago. Delphine Herbert reports.
