Harrison's is better than Zupreem... or at least it should be. Harrison's doesn't have dyes in it, nor does it have table sugar....
When Charlie ate Zupreem Fruitblend, his droppings were loose and colored. What if he ended up with blood in his droppings? How would I know if they were dyed?
If a bird eats dyed pellets and the droppings aren't dyed, where is the dye going?
When I put Charlie on the Zupreem Natural, his droppings became normal color and shape.
On Harrion's, he's become pudgy...
Jayde, my new girl, lost weight on the trip over here. Since introducing Harrison's into her diet, she's put the weight back on, and I think she now weighs more than she did in her previous home! (but she's not fat)
I'm also trying to get my bourke parakeet to gain weight, and as per yesterdays meal, my bourke parakeet, which weighs about 3 1/2 times less than Jayde can apparently eat the same amount of food as her...

My bourke is underweight and has some health problems, so I'm hoping that the Harrison's can help her gain back the weight she's been missing for years, and maybe help her immune system.
