The Association of Avian Veterinarians recommends the following diet for a parakeet: 50% cooked beans, whole wheat bread, cooked rice, pasta, and seed 45% fresh broccoli, carrots, yams, spinach, dandelion greens, other green/orange fruits and veggies 5% eggs, tuna packed in water, well cooked meat Parakeets do NOT overeat. If anything, people tend to give them too little food, thinking a seed cup is full when really it's just full of the hulls of the seeds the parakeet has already eaten. Be sure to refill your parakeet's food supply daily and to give him or her lots of fresh foods too. Source:
