Mix a very small amount of water with a few drops of each color of food dye. Color three cups of birdseed with the dye, one cup of seed per color. Take care not to get the seed too damp or it will rot. Allow the dye to dry quickly and thoroughly. Fill each bird feeder with the same amount of birdseed, one color in each.
