I would like to hear what other people have to say about this as well. Neither of my cockatiels like sunflower seeds very much anyway, and really they should only be a treat and not a major part of their diet. But almost every brand seems to have sunflower seeds in it. I could almost forgive the sunflower seeds, they are not that hard to pick out. But what i really don't like is all the additives in store bought bird seed these days. Coloring, artificial flavors, and pellets that aren't really that healthy and my birds don't eat anyway. I buy Roudybush pellet and like to supplement their diet with a variety of healthy seeds. I've started buying human grade seed at the grocery store to feed them, but I've not perfected the mix yet.
Zupreem is a pretty good pellet brand. If you are not already feeding your birds pellets, this would be a good way to introduce them into their diet. Personally, I don't like any artificial colors in my birds food. I don't like it in my own diet, so I don't want it in theirs either. But that's really a personal choice.I found some on Dr.Foster and Smith, I might buy a bag.
