agreed and well putPersonally I don't worry about it too much. I don't think that knowing the daily needs would be of any practical use- in order for it to be so, you would have to know exactly how much feed your chicken is eating (like if it's 9g of protein they need and there is 9g in 5 oz of feed, that's worthless info unless you know each hen is eating 5 oz, which in fact none of us can know for a variety of reasons...). Percentage is a more practical way of figuring it, because the proportion of nutrients is more important than the total of any single nutrient. The closest I come to worrying about it is in the winter, when I almost completely exclude any scratch grains so I don't lower their overall protein too much. BUT I do completely agree re: the animal protein- I wish more commercial foods contained them.
