How Long Do Parakeets Live? Parakeets tend to live 10 to 14 years, if in good health. Not all will live that long, however, since parakeets can fall ill even with proper care. Improper care can shorten their lifespan to a mere 4 years or less. Consider these parakeet care tips.
Seeds. Parakeets love to eat seeds, but the amount of seeds you feed your bird should be kept to less than 10 percent of the total dietary intake. Feeding bird seed alone is not a balanced diet for your parakeet.Seed diets often contain low levels of certain vitamins and minerals he needs to stay healthy.ggs provide protein as well. Parakeets that don't get enough sunlight may need supplemental vitamin D to help absorb dietary calcium. Vitamin D can be given by feeding them less than 1 mL of cod-liver oil mixed into 1 kg of food. Parakeets can eat most foods you eat, such as whole wheat toast, cooked pasta and chicken.
