Dubbing, little one, is a process of removing a chicken's comb (that red thing on top of their head) and sometimes their wattles (those floppy things on their neck). Some people do it because they believe it makes them look better for shows and competitions or to prevent them from fighting with other chickens. It is done by a skilled person who uses a sharp tool to cut, cauterize, or pull the comb and wattles off. It's important to note that dubbing is a controversial practice and is illegal in some countries.
