Hi Kathy... you have tried EVERYTHING that I can think of to remedy this pr
problem. I have some birds in the past that did the same thing and I
believe it somehow tied to their maturing and growing process, but I can't 
be sure of this.  The only thing you might do thats diffent is to add
lactobacillus to the formula. This may increast the flora in the digesting 
track and aid in better digestion.. I firmly believe in this process and
Necton tonic.. these two things are unbelievable.  I have seen it pull
birds back from the brink of death.  I'm sorry I can't be of more help,
but I will bring it up with my friends at the bird club.  Until then good
luck and keep on birding.    ]
