For those of you having difficulty converting your birds, it's most likely because your birds are addicted to the sugar in the Zupreem. Zupreem has a lot of sugar in their pellets (sixth ingredient), so your birdies have a sweet tooth, I'm afraid. As long as they will eat fresh foods well, you can always try just switching to a different pellet cold turkey and then waiting it out. It won't hurt them to be without pellets for a few days or weeks and eating fresh foods only until they decide to try the new pellets. Remember that it takes a minimum of 28 days for brains to rewire themselves, so it could very well take a month for a sugar addicted bird to decide that sugar-free food is actually pretty yummy. There are also other ways to do a diet conversion, but it's late, I'm tired, and I don't feel a particular need to monologue right now. If you're interested in some other ideas, though, let me know and I'll do something about it later.
