Looks like I need more diversity in the grains. This could very well get thrown in the "too hard" basket! As much as I would love to DIY it, it is really hard to get the formula right. Then all the mixing??
@Anniebee I would feed the flaxseed whole. They are little seeds and the oil goes rancid too quick if they are ground.
It is a bit of a science , getting it right and can be cost prohibitive. I like this article. While discouraging home mixes, it still gives a recipe.
