It is all right to allow the bird to sample food from your plate, if you want to let the bird eat at the table. But don't let the bird eat from your mouth, or off a utensil you have already put in your mouth. The bacteria in your mouth can make your bird sick, as their bodies have different natural bacteria than ours. Avoid the kind which is pre-packaged, as it is usually not fresh. You can also soak the millet spray in water overnight to soften it up before feeding it-many birds like it better this way.
Sprouted seeds are a good source of vitamins.
You can sprout your own birdseed by placing two tablespoons of seeds in a clean jar, and tying several layers of clean cheesecloth over the jar top. Rinse the seeds with lukewarm water, and drain through the cloth. Continue rinsing till the water comes out clear. In two or three days, the seeds will soften and start to sprout roots. Use them before they grow leaves.
