NEW YORK (TheStreet) -- Shares of Shake Shack (SHAK) are rising, up 1.08% to $91.68 in pre-market trading Thursday, after the burger joint applied for a "chicken shack" according to its subsidiary SSE IP's recent trademark filing, CNBC reports.
"Shake Shack was born from a fine dining company, and we constantly test new menu items in our test kitchen," the company said in the statement.
Shake Shack has yet to announce any new items or initiatives.
Research firm NPD Group found that chicken meals rose 3% to $5.4 billion for the year ending in March at fast-food restaurants, CNBC added.
That figure was higher compared to the 1% rise in burger servings, which resulted in $7.9 billion for the year, CNBC noted.
In yesterday's session, shares closed at $82.85 on heavy volume.
New York City-based Shake Shack is a roadside burger stand serving an American menu of burgers, hot dogs, crinkle-cut fries, shakes, frozen custard, beer and wine.
The company operates about 63 casual dining restaurants around the world.
