Yes, but they really need to eat the larger grains found in cockatiel seed. In addition, all seed is a poor diet for any parrot. They require a variety of healthy, nutritious foods also.

The weed and feed should not affect the seed although you should give it a couple of weeks to react.
It eats fruit and nuts.
if it is a seed, you should be able to plant it. try soaking it in water first, to give the plant a jump-start

They love millet spray and my lovebirds really like safflower seeds. I mix safflower seeds with a parrot seed mix.
A seed can give you food.
Sparrow's feed mostly on seed but you can give them live worms/maggots as well.
Impossible. Until it sprouts, then you should not give it so much.
Eclectus parrots in the wild feed primarily on native and rainforest fruits and nectar as well as berries. They do eat seeds, but are not seed eaters as much as many other parrot species. Many people who keep Eclectus parrots make the mistake of feeding them a seed-based diet, but this is not the best diet for them.
