Dried Chicken Feet are used in the practice of Voodoo, as well as other magical traditions, for protection and for enemy work. The feet are believed to be powerful protection against evil doers and are believed to work by magically "scratching" one's enemy.
When it comes to Voodoo, Hoodoo, and other practices of those from Africa, the foot of a chicken has always held a very powerful and special meaning. They can be added to any magical practice, just be sure to acknowledge the history of this magical act.
Oftentimes used as charms and talismans, chicken feet are a wonderful addition to any spell that involves protection; be it protection in your love life, protection in general, protection of your belongings, etc. My grandmother would usually use them to protect from dark energy, evil spirits, and psychic attacks. If you would like to use them in the protection of your home, it is best to leave them near the front door.
The way in which the chicken foot works is based in how chickens usually react when messed with. Imagine a chicken scratching you with its legs. Ever had that happen?… It hurts. One can also use chicken feet to curse someone by leaving one on their property with the proper intent. I’d suggest burring it outside the room they spend the most amount of time in.
When it comes to how to get them any old dried up chicken foot will do. You can usually buy them in a lot of places, including pet supply stores as they can be used as treats for dogs. A little personal preference of mine is to paint them. Especially if using one as a charm. Paint anything on it really. This helps preserve it and keep animals away from it. I usually paint it black and draw symbols having to do with my intent in red.
