A bird flu outbreak at two egg farms that forced half a million chickens to be culled could rob supermarket shelves of 450,000 eggs per day, as farmers warn biosecurity measures may push up prices.
An outbreak of avian influenza has been confirmed at an egg farm in Terang, 200km southwest of Melbourne.
The site is linked to the Meredith egg farm, about 130km away, where a mass culling of chickens took place on Wednesday after a number of poultry died from a different strain of the same virus, H7N3.
