I bought millet from a certain feed store and it's very light tan and the size of bbs (as in a bb gun). I've been using it for scratch and the hens love it better than oats or wheat. Last week I bought millet again (but from a different feed store) and it's light greenish/yellow and super tiny. I can't use it for scratch because it's just too tiny. What gives? And is there a difference in the protein percentage because I will have mix the super tiny green millet into the feed. Millet is supposed to be 9% protein, but if the super tiny green millet is just dehulled millet, then wouldn't it be higher in protein than the tan bb-sized millet?
