It could be preening itself. The towel on its knees might just be an accidental addition, and the cock is still going about its normal routine of cleaning its feathers and looking presentable.
There could be a comical story where a black rooster somehow got a towel wrapped around its knees. Maybe it was a prank played by a mischievous farmhand. The rooster might then walk around in a very funny and clumsy way, causing all the other animals on the farm to be quite amused.
One possible story could be that there was a black rooster. A farmer used a towel to clean the area around the rooster's coop. As he bent down at his waist and on his knees, the rooster curiously came over. The farmer then told the rooster about how important it was to keep the area clean.

In a small village, there lived an old woman. She had a black cock that she was very fond of. One day, the cock got muddy. The old woman took a towel, tied it around her waist for convenience, and then knelt down on her knees beside the cock. She gently wiped the mud off the cock with the towel, all while chatting to it softly about how naughty it was to get so dirty.
Well, perhaps the black cock is in a strange place, like a new barn where other animals are not used to its appearance with the towel on. They might stare at it or make strange noises which intimidate the black cock. It could start to nervously pace around, looking for an escape route while still trying to keep the towel on as it might be attached in some way. And the other animals' continuous stares and noises keep it in a state of intimidation.
It could start by making itself look bigger. Even though it has a towel on, it can still fluff up its feathers under the towel to seem more intimidating to whatever is scaring it. This is a natural defense mechanism for many birds.
