Yes you very much so want to make sure your feed has the proper proportions of protein and other good shit.

I'm err on the side of not telling people specific ingredients because everyone has different things at their disposal.

I would use tools like this and Google around, as always DYOR and verify.

It's a bit more daunting obv, I raw dogged it with no calculator like this one - just using my intuition coupled with what I read online.

I find that every journey is the most successful when you trust yourself so if you have any specific questions, I would love to answer them to the best of my abilities meanwhile you're on this journey - but I won't rob you of the journey my friend!
