I offer the science. What you do with it is up to you.Hello I understand now. I'm sorry, the reason I was asking is because @JacinLarkwell liked that you laughed at what I said, except @JacinLarkwell only laughs at me in an unpolite manner to support @U_Stormcrow in discouraging me. So I thought since she liked your laugh that it was a making fun of me laugh.
I would *encourage* you to spend more time concerned with your birds' welfare, and less time concerned with your feelings or the latest feed fads. Once you have greater understanding of the way all the various parts work together to make a successful whole, you can then make an educated decision for your self and your birds as to which tradeoffs are acceptable, which are not.
