Like Scott, I feed Zupreem Fruit Blend along with in-season produce, a bit of what we eat, cooked, enriched bird bread, a few nuts as training treats, and sprouted seed. They both came to me from their breeders on Zupreem (and Scenic hand-weaning pellets). Both my larger parrots are over a decade old and super healthy, non-pluckers, and neither has fatty tumors or health or temperament issues. They have beautiful feathers, so I can't believe this food is "bad" for them. Over the years I've tried to switch them due to peer pressure mostly (my vet seems fine that they eat Zupreem as their base diet), but they flat-out refuse to eat Harrisons and while they will eat Roudybush here and there they always quit eating it after the novelty wears off. Foods come and go, trends heat up and cool off, some foods are discontinued, new ones pop up again, but I think I'll just stick to my feeding regimen because it seems to work for my flock.
