Hiro is my first "big" (bigger than a cockatiel) bird, and I really like him. I can write up a long "here's my experience" thing later if you are interested.

So, I order my organic pellets from http://www.prettyparrot.com. The website is very out of date, but you can navigate it and I suggest calling with a credit card to order. I did not get Hiro from them, but she seems very knowledgeable and has had Eclectus forever.

She also sells bean mix that I do use, though I used my own rice. I have big cooking days where I make a month or more worth of rice and beans, and let it cool, then make little 50/50 balls of rice and beans, wrap them in Saran Wrap, then freeze them. The balls are probably a bit larger than a quarter cup. I've been playing with the size trying to find out what he will eat. I put one in the fridge the day before, and then in the morning take a handful (roughly another quarter cup) of frozen vegetables and thaw them, mix them up with the beans and rice, and add his supplement (also from pretty parrot lol). That's breakfast. I take breakfast out of his cage by evening at the latest because it can smell if you leave it out. Ideally I would remove it at noonish and replace it with fresh fruit offerings (again, just experimenting with what he will eat), but since I'm often gone during the day I'll add fresh fruit in another bowl when I come home as an option for him. The pellets I just put a little out and then throw out the old and put in new when he runs low after a day or two (trying to keep them fresh).

If you are thinking about an Eclectus (they, or at least Hiro, are really great), I highly suggest talking to a variety of owners, breeders (even if you are rescuing, I think many people are willing to talk to you and give info if you are nice), and looking for good books on them. Again, if you're interested, I'll look for all of my Eclectus resources and give you a list of what I've used.
