ChickenShades - Customizing Creature Appearance
ChickenShades is a client-side mod that adds an additional graphical layer to various creatures in the game. By itself, this modification doesn't introduce visible changes, but when using a special resource pack with textures located in the assets/chickenshades folder and having the naming format [entity registry name].[visible name].png, it starts displaying these textures as an additional layer over the standard model.
The classic example of the mod's work is the famous chicken shades by Vaygrim. For a regular chicken, the texture should be named chicken.vaygrim.png, and if using a chicken from the Chickens mod, the file name will look like chickens.chickenschicken.vaygrim.png - quite lengthy, but functional!
