Yes they are made from Keratin Protein
Feathers are a solid material. They are made of keratin, a protein that forms a strong structure in the form of strands in feathers. Feathers can be flexible and soft, but they are still considered a solid material.
Your hair is composed of the protein keratin, which is the same protein that makes up fingernails, feathers, claws and hooves.

Yes nails are made from proteins. So are feathers and hair
Feathers are primarily composed of keratin, a protein that also makes up human hair and nails. Keratin molecules are organized into a complex structure that gives feathers their strength, flexibility, and ability to repel water. Feathers may also contain trace amounts of minerals and pigments that contribute to their coloration.
Feathers are primarily made of keratin proteins, specifically alpha-keratins, which provide structure and strength to the feather shaft. Other minor proteins found in feathers include beta-keratins, which are present in the barbs and barbules of feathers, contributing to their flexibility and elasticity.
They are all made of keratin.
Penguins are birds and feathers cover their bodies, not fur. Some in ornithology believe that the 'chemical composition of feathers is about 91% protein, 1.3% fat and 7.9% water'.
They stockpile extra muscle proteins prior to molting, which then supply amino acids for protein synthesis.
To make paper out of chicken feathers, first collect and clean the feathers thoroughly. Then, grind the feathers into a fine pulp using a blender or mortar and pestle. Next, mix the pulp with water and a binder such as starch, then spread the mixture on a screen to dry and form into paper sheets.
Hair and bird feathers are both made of keratin, a protein that is also found in our skin and nails. However, the structure and arrangement of keratin in hair and feathers are different, resulting in their unique characteristics and functions.
Feathers primarily consist of the protein keratin, which forms the structural framework. They also contain pigments that give feathers their color, as well as trace elements like calcium and magnesium for additional structure and strength. Additionally, feathers may have oil-producing glands that help maintain their flexibility and waterproofing.
