I just found out that my feed store has game bird starter which is 30% protein. I have chickens and wanted to know what is the highest protein percentage I can give to my chicks? The reason I want to give them game bird feed is because of the animal proteins. I planned on mixing an 18% chick starter and the 30% game bird starter to give me 24% chick feed. What would the average protein be if I mixed 75% of 18% protein feed and 25% of 30% protein feed? I am not very good at math lol and I know this is confusing! I think that if I mix 75% chick starter and 25% game bird feed then I would have about 21% protein average. Am I right? Should I even go through the hassle of mixing?
