I want to up the protein in my chicken feed as I am starting to have some low protein issues. At present, my feed has 15/16% protein and I would like to get it up around 18% to 20%, especially during this up coming molting season. I have some organic egg protein powder at hand. One scoop is 25 grams protein. Here is where I am confused. How many scoops would I add to a pound of feed to get the protein up where I like it? And this goes for any other proteins I add. How do I know how much to add to bring it up to a level that I will know on average how much protein I am giving them? Thanks so much!
