I have baby silkie chicks on purina start and grow but plan on changing to purina. I had a couple questions about it. Do all nutrena feeds have animal proteins? What kind of animal protein does it have then? I know protein has been a big argument around here lately. I also want to know about the game bird feed. When and what ages do I feed game bird feed? Do I feed it even while they are laying and growing? How is the quality? This is the only brand of feed that is is available and has (I think!) animal proteins. I would really like to know when I should use each feed and what are the benefits. Any info would be great! Ohh the reason I am asking this question on here is because the site doesnt have a lot of info and ingredients.
