Shake Shack appeared to throw some shade towards Chick-fil-A when announcing a free chicken sandwich only-Sunday promotion during the month of April.
“Here at Shake Shack, we pride ourselves on our Chicken Shack which is available 7 days a week,” the fast food restaurant chain wrote in a press release, appearing to point at Chick-fil-A’s closed on Sunday policy.
The burger joint pointed to their antibiotic-free chicken — apparently highlighting Chick-fil-A’s recent announcement that they are shifting from antibiotic-free chicken starting this spring.
“With crispy, white-meat chicken breast over lettuce, pickles, and buttermilk herb mayo on a toasted potato bun, this sandwich outshines its competition. And what makes our Chicken Shack even better, is that it’s made with antibiotic-free chicken, something not everyone can say these days…,” Shake Shack quipped.
CHICK-FIL-A SET TO SWITCH FROM ANTIBIOTIC-FREE CHICKEN
The New York-based chain touted its antibiotic-free chicken in a poster.
“Eat More Antibiotic-Free Chicken,” Shake Shack announced.
Chick-fil-A said that their switch from antibiotic-free chicken came due to supply reasons.

“As we look to the future, the availability of high-quality chicken that meets our rigid standards has become a concern. This change enables us to not only ensure we can continue to serve high-quality chicken, but also chicken that still meets the expectations our customers count on us to deliver,” a Chick-fil-A spokesperson told Fox News Digital in a statement.
People can score the Chicken Shack (Shake Shack’s chicken sandwich) for free on April 7, 14, 21 and 28 at participating locations.
To apply the promo, customers must place a $10 minimum order on an in-store kiosk, the Shake Shack app or the restaurant’s website.
