Keratin on the beak is shed from the outer surface of the beak, while being replaced from underneath by new keratin. Occasionally these old layers are not completely molted or shed which leads to thickening on the outer surface of the beak, known as hyperkeratosis. It is often referred to as a crack on the beak.
