Chicken anatomy varies between breeds. Some have functioning Barbicels and some don't. some have one comb and some don't
Feather Types
Standard: Standard feathers are just regular features seen across a variety of bird species and many chicken breeds have this kind of feathering.
Silkie: Silkie feathers are the feathers of Silkies as well as many other breeds. Breeds with this kind of feather can't fly due to the lack of functioning Barbicels 
Frizzle: Frizzle feathers are a kind of feather that curls upwards rather than lying flat against the chicken, which gives them a very unique look. While the Frizzle gene can occur in different breeds of chickens, some countries recognize the Frizzle as its own breed. Like Silkie feathers, chickens with frizzle feathers are unable to fly well due to their unconventional shape.
Comb Types
Across chicken breeds, there are different types of combs. Combs are the “Mohawk-like” Protrusions common among Hens and roosters alike.
Buttercup combs: These are combs that resemble Deer Antlers to a certain extent. From the Side, they can be mistaken for Single combs. An easy way to distinguish this Comb from Single Combs is by the ridges. Buttercup combs tend to have more ridges and the other side of the comb can be spotted at angles.
Pea Combs: Pea Combs resemble tongues and have lots of tiny bumps on them. They are generally one of the flattest comb shapes.
Single Combs: Single Combs are the most Iconic comb types. They resemble Mohawks and are found across many breeds such as the Iconic Leghorn and has been the most recognizable part of many breeds.
Walnut Combs: These combs are vaguely circular combs found on some breeds such as the Silkie. Their shape can get mixed up with other round combs such as Strawberry and Cushion.
V Combs: V combs are just as their name states, V-shaped Combs. Their shape can vary as some chickens with V combs can have more “antler-like” V combs while others can have more horn-like ones.
