New York City's transit agency is investigating a video posted online that shows a man kissing and snuggling a live chicken aboard a subway.

Spokesman Charles Seaton said Thursday it was looking into whether the Tuesday incident on the uptown No. 6 train was a prank.

He says no passengers reported it.

The video shows the man hugging, kissing and caressing a chicken as he lays on the subway train's floor. Some passengers look on and laugh, while others seem to be hustling out of his way and into the next car.

The video was posted on a riders blog, YouTube and was picked up by Gothamist, a local blog network.

The blogger wrote that the man seemed oblivious to his surroundings.

Seaton says only service animals and those in containers are permitted in the subway system.
