2 is my limit for the time being. The only thing I haven't enjoyed after adding a second bird is the additional clean-up. I thought a smaller bird would make less of a mess but I was very mistaken!
Finding the time to spend with each bird individually hasn't been an issue. I take Pele out first and she's happiest being on me hanging out and using me as a jungle gym while I do homework or housework. She really doesn't care what I'm doing as long as she can be with me. Mojo is a little more hands off so I have him out while we're relaxing or while I'm doing things around the house that I can't do with a bird on me. He sits down with me for some cuddles for a few minutes and then flies to his play stand to do his own thing. Whenever he wants attention he'll fly or walk to me or call to me for some scritches. I only do training once or so a week so that hasn't been an issue.
Feeding hasn't changed as they both eat the same pellets and eat the same fresh foods. Toy expenses haven't increased a noticeable amount because Pele's toys are much smaller and cheaper than Mojo's.
The reason my two birds really work for me is because their personalities are different. I can find a way to have one or the other with me for the majority of the day when I'm home. When I'm doing something that doesn't suit one it will usually suit the other one so it will be their turn to be out.
