All domestic chickens have a crest on their heads.
All domestic chickens have a crest on their head. It is a fleshy appendage, very large and brightly colored, especially in roosters. The best known is the serrated crest, which looks like a burning fire. But there are also crests in the shape of a butterfly, a rose or a polka dot.
Fun fact: A bright red crest indicates that the rooster is healthy.
