I don't recommend Zupreem due to the dyes they have in their pellets and the fact that the 5th ingredient is sugar.
Also corn, wheat and soy are filler ingredients, soy is probably the #1 culprit behind parrot hormones, corn very close behind due to the sugar content.
I use TOPs for my 9 parrots, they all love them and to me, they are the best pellet, they have to artificial vitamins, preservatives or minerals.
You can get a 10lb. bag of their pellets on their website for $37, if you order it on Amazon they WAAAY overcharge as much as double the price.
I can't recommend another pellet because I don't feel like any compare to TOPs.
