My favorite is the Chinese mung bean which is very easy to sprout and possesses a high degree of palatability for the birds. I have also used soy beans for sprouting. My birds do not like alfalfa sprouts. Sprouting seed is the simplest way to provide your birds with fresh greens. For a few birds only a quarter cup of seeds should be sprouted at a time.
Seeds increase in volume tremendously when sprouted.
Place the seeds in a clean glass jar. Fill with tap water and let stand at room temperature for twenty-four hours. Rinse and drain completely. Repeat the rinsing and draining completely daily until the seed has sprouted. If a foul odor or mold develops, discard.
