Popeyes and Chick-fil-A are feuding on Twitter as a battle over chicken sandwiches reaches a boiling point.

Earlier in August, Popeyes added a chicken sandwich to the menu. It was an immediate hit, with Business Insider's Irene Jiang naming it No. 1 in her ranking of fried-chicken sandwiches.

However, Chick-fil-A, the self-proclaimed inventor of the chicken sandwich, refused to accept the elevation of the new chicken sandwich without taking a stand.

"Bun + Chicken + Pickles = all the ❤️ for the original," Chick-fil-A tweeted on Monday.

Many took the message as a subtweet of Popeyes, as people are increasingly comparing the two chicken sandwiches.

Popeyes quote-tweeted it, adding: "... y'all good?"

The battle between the two chicken sandwiches has been a major topic of discussion on social media over the past week.

Jiang published a direct comparison of Chick-fil-A and Popeyes' sandwiches on Monday morning.

"Chick-fil-A's sandwich isn't bad. Just like everything else the chain offers, it's reliably OK," Jiang concluded. "But Popeyes' sandwich is a handful of heaven. And even though it's much larger, it costs a dollar less."

Others agreed, crowning Popeyes the new king of chicken sandwiches.

Neither Popeyes nor Chick-fil-A immediately responded to Business Insider's request for comment on the social-media feud.
