Let me state right up front.  I am NOT an experienced peafowl breeder or even owner.  So feel free to ignore what I say.  Hopefully someone will address your question.
As a VERY experienced animal caretaker, including poultry, the ingredients of this food would seriously concern me.  What does it consider "grain products"?  It really sounds like this feed is made of by products from the manufacture of some other feed/product.  That said, there is no guarantee that it has any usable food value. Hopefully below is a link to the terms used for feed description.  Over and above that ,19.5% of it is undigestable.  What is it?  Sorry the site won't allow me to link the description of terms to you.
