Wendy’s is entering the Twitter battle over which fried-chicken sandwich reigns supreme.

On Monday, Chick-fil-A’s apparent subtweet of Popeyes’ new fried-chicken sandwich set off a social-media frenzy.

“Bun + Chicken + Pickles = all the ❤️ for the original,” Chick-fil-A tweeted.

Popeyes – which recently rolled out a new fried-chicken sandwich – quote-tweeted it, adding: “… y’all good?”

Twitter then exploded with a debate over the battle between Chick-fil-A and Popeyes fried-chicken sandwiches. Neither brand responded to Business Insider's request for further comment on the social-media feud.

Later on Monday, Wendy's decided that it needed to add its two cents to the chicken-sandwich conversation.

"Y'all out here fighting about which of these fools has the second best chicken sandwich," Wendy's tweeted on Monday afternoon.

Popeyes felt the need to respond to the second subtweet of the day.

"Sounds like someone just ate one of our biscuits. Cause y'all looking thirsty," Popeyes tweeted.

Wendy's quote-tweeted Popeyes' tweet, adding: "lol, guess that means the food's as dry as the jokes."

The battle continued on Monday night, with Popeyes quote-tweeting Carter Wilkinson, the teenager who recieved free Wendy's nuggets for life after being retweeted more than 3.4 million times.

Wilkinson had tweeted: "how many retweets to never tweet again?" Popeyes added: ". @Wendys even Carter wants you to stop."

Wendy's responded by mocking Popeyes for its technical difficulties posting the tweet, which it deleted multiple times before correctly formating.

Unlike Popeyes, Chick-fil-A has kept a low profile on Twitter following Popeyes' quote tweet. Boston Market, however, decided to attack the chicken chain on another front: Chick-fil-A's new mac and cheese.

"Customer: Can I get something like Boston Market mac & cheese but mediocre? Other guys: My pleasure," Boston Market tweeted, a clear reference to Chick-fil-A's customer-service policies.

Wendy's and Boston Market did not respond to Business Insider's request for comment on the subtweets.

Chick-fil-A's rapid US expansion is perhaps making it a target. The chicken chain became the third-largest chain in the US by sales in 2018, with $10.46 billion in American system-wide sales, and it is steadily expanding, with plans to open its first store in Canada by the end of the year.

Business Insider's Irene Jiang has taste-tested fried-chicken sandwiches from Wendy's, Chick-fil-A, and Popeyes, as well as mac and cheese from Chick-fil-A and Boston Market, in recent weeks. Her verdict: Popeyes' chicken sandwich reigns supreme, but Chick-fil-A's mac and cheese edges out Boston Market's.
