Ok, thanks, I'll just do half and half. How much a day should one cockatiel get?

Tikeyas_mom -- If he doesn't like it, you should try adding some vitamins to his water. The only problem with that is that you have to watch him to make sure he's actually drinking his water, because if a tiel thiks the water tastes funny he won't drink it. It is also a breeding gorund for bacteria, so the water will need to be changed about 3 times a day. But atleast he would be getting his vitamins...

I read that the avarage lefespan is 15-20 years, but a very healthy tiel can live to 30.
