I just adopted 2 parakeets from my neighbor who is in the hospital.don"t know the sex but they are in a large cage and get along.one is 2 or 3 years old the other is about 6 months old. how long do they live? they came with food the brand is hartz bonanza parakeet diet tropical blend compete nutrition is this OK to give them. it looks like mostly seed.I think this is all they have been fed.why I say this is because the person is elderly and has home health aides with her and her son gets the bird food for her. they look healthy to me they have been chirping.all advice welcome sorry for the long post.
