This is our regular go-to food for our 7 parrots. We buy the big bags and put it in freezer bags and freeze it. Very happy with the zupreem pellets
My GCC liked this food and had no problem adjusting from a seed diet to this. My main complain with it is that it made her poop orange, which stained anything white. For the above mentioned reason I switched her to a food without dyes.
I transitioned my birds from a seed only diet to this pellet. While the transition was fantastic, I found that they were bouncing off the walls, screaming out of control. While this diet is better than seeds, I would not recommend keeping birds solely on this brand of pellet
