Well, while searching the Hagan website I found this in the Q&A section:
Soy in Parrot Food
Question
I have been reading a lot about soy in food for birds as well as cats, dogs and humans.
Is the soy in your food dangerous for birds?
Answer
We are quite aware of the small danger of using uncooked and unfermented soy in pet foods. We do not use this form of soy for our various pet food products. Instead, when we do use soy, we use completely cooked and well processed Soy Bean Meal. Our full cooking process destroys the Trypsin inhibitors, secondary plant compounds and removes the oil as well.
All we want to incorporate into our foods is the excellent protein that is left.
Then we mix the soy bean meal with 85 percent by weight from EIGHT other grains and nuts. Once thoroughtly mixed we then extrude it for another 30 minutes at high temperature.
Our Fat content listed on the packages comes from mutltiple sources as does our Protein including Sunflower and roasted peanuts.
Parrots that eat our Tropican look amazing and we are breeding second generation birds at our HARI breeding center:
Home Birds - then the HARI selection on the left menu
So yes, we agree that raw soybean is not very good for avian, or many other nutritonaly requirements. Our resaearch long ago precluded its use and that certainly is not what we put in our Parrot Foods.
Not sure this answers the question though.....
