Sienna and Lara know that eggs are a subject worth getting your feathers ruffled for.

The sisters, pictured in Werribee, are looking forward to World Egg Day, which is celebrated on the second Friday in October.

The day was founded by the International Egg Commission (IEC) at a 1996 conference in Vienna. The idea behind the day is to raise awareness of the important place which eggs have in human nutrition.

According to the Australian Eggs organisation, consumers now eat 35 per cent more eggs than they did a decade ago, with the average Australian enjoying more than 18,100 in their lifetime.

Australian eggs are now so popular that about 15 million eggs are eaten every day, which reflects annual consumption in Australia of 5.5 billion eggs per year.
