...The birds will eat it.

How do animals survive without a human nutritionist?

Just let the birds decide for themselves what they consider to be disgusting or not.
It works in the wild, at least.

Saw 2 young men which went out from a corner. They were drunk. One of them have noticed me and made a gest to me. I've looked at him. He was ESE. He smiled to me. His pal near have asked "To who you are gesting?". He've said - "to a human". The pal has replied rudely with the sense "just another face".

It's called natural selection. The birds which had bad tastes - do not sing anymore. The same as people without good own thinking and without experts help.
There is many new food which animals never met before to develop adequate tastes and it's hard to say how much of them get health issues from bad food now.
