Wendy’s Co. said Thursday that it’s launching the Bourbon Bacon Cheeseburger, offering the item for free between May 6 and May 9 with a $15 purchase on Postmates. The launch is notable after months in which fast-food chains have battled over dominance in the chicken category, with competitors like McDonald’s Corp. among those launching chicken sandwiches. Chicken has become so prominent on fast-food menus some say it has contributed to a chicken shortage. “Following the success of our Pretzel Bacon Pub Cheeseburger and Jalapeno Popper Chicken Sandwiches on the Made to Crave platform, we wanted to go back to our roots,” said Carl Loredo, Wendy’s chief marketing officer, in a statement. Wendy’s is scheduled to report its first-quarter earnings on May 12. Wendy’s stock is up 4% for the year to date while the S&P 500 index has gained 10.5% for the period.
