 Bird flu is contributing to an egg shortage in Australia. Here's reporter Scott Maimon. The outbreak of bird flu H7N8 strain has led to chickens being destroyed at a variety of properties. Farmers Federation spokesman Xavier Martin, he says while chickens are being culled... There's still plenty of supply. Australian supermarkets have limited the number of eggs that can be purchased, but overall, he says, there's still plenty to go around. So there's no need to panic buy.
