I currently use Harrison pellets as well and they are SO worth the price. Ive been caring for a lovebird that plucks when stressed and bought these pellets hoping they might help in some way, Im not sure how but after all the vet visits and medications, you start to get desperate and hopeful for any miracle claims. But with everything mentioned above I think in the least it would give them a yeast infection from all the fruit sugar, and who knows what else. I do wonder on their truth behind the claims of parrot pellets being based off of poultry feed and how different their digestion is to chickens impacts their digestion/nutritional aspects. But better safe than sorry.Pellets don't need many ingredients, I use Harrison's. A great bird food. I knew it was one of the best bird food, but I didn't get it because I thought it was super expensive. It actually is not!! Birds love it and It's all organic.
