The easiest way to prevent chickens from attacking a specific plant is to built a fence around it. A simple fence made with chicken wire and some form of support will usually be enough to keep the pests away.  Insert a tomato cage over the plant you need to protect or surround the plant with two to four stakes. Wrap the chicken wire around the stakes, weaving the stakes into the mesh vertically so that the entire structure remains secure. The entire structure only needs to be 6 to 12 inches (15 to 30 cm) tall to keep most chickens out. If you want to protect a broad area of mulch, recently sown seeds, or seedlings, you can usually do so by spreading a wire cloth over the entire patch of ground. Most chickens won't like the feeling of wire beneath their feet, so they will tend to stay away.  Purchase wire deer netting with relatively small holes and spread a sheet over the entire area you wish to protect. Secure the edges of the of the netting with heavy stones or bricks to prevent it from coming off. Alternatively, purchase wire hardware cloth and cut a rectangle large enough to cover the area you wish to protect. Cut a small square out of each corner and bend all four edges down at the newly cut corners, creating perpendicular "legs" for the wire mesh to stand on. Place the makeshift wire box directly over the area you want to protect. It should remain secure without additional help. Another way to protect an individual plant is to completely surround the base of the plant with bricks or medium to large stones. The stones must be large enough to prevent the chickens from moving them.  Wait until the seed sprouts before surrounding the area with stones. That way, you'll know exactly where the base of the plant is located and won't accidentally cover or block it. Try to use stones that are at least 6 inches (15 cm) in diameter or width. Anything smaller than this might be too lightweight and could be knocked over by notably aggressive chickens. Keep the base of the plant completely surrounded by a perimeter of...
