Chicken question

It's a while since I've seen an ad for Red Rooster Chicken but I would swear that it used to be "Red Rooster chicken is barbequed ..." which is why I was surprised to read an ad in the Daily Telegraph this morning for a "mouth-watering franchise opportunity" (Red Rooster) offering people the opportunity to "be part of Australia's largest home-grown, oven-roasted chicken business ..." (I knew this not watching television would lead to confusion!)
