New survey reveals Australia's favourite supermarket roast chicken

The humble roast chicken has become a dining room stable across Australia, and now a new survey has found which supermarket chook rules the roost.

Consumer research group Canstar Blue has put in the hard yards, surveying more than 1,500 Aussies to see which major supermarket chicken takes home the top spot.

The results are a surprise to some, with Megan Birot from Canstar revealing their testing criteria, roasting each chicken for its taste, freshness, packaging, and value for money.

The annual ratings in the poultry category reportedly one of the most sought-after product reviews by both customers and food outlets.

"We went out and we surveyed 1500 consumers to ask them to rate the roast chickens they've recently purchased from the major supermarkets," Ms Birot told 9News.

Surprisingly, supermarket giants Coles and Woolies scored the lowest, with both their $10 chickens getting three stars for overall satisfaction and taste.

The Coles RSPCA-approved roast scored slightly higher in the value for money category, landing a four.

Reigning-champion IGA was pushed down to second place, with its $11.50 bird rating four stars overall.

Newcomer Costco's $6.99 chickens took out the top spot, landing a perfect score across all categories.

However, poultry perfection comes with a price as shoppers needed to get an annual $60 membership to access the growing number of national stores.

Canstar said the weekly savings on chicken alone is enough to justify the price.

"If you shop there regularly, then you've already got your money back on your membership, and that's just a great option to save on your weekly dinner," Ms Birot told 9News.
