So far I have looked more closely at the brand and their feed for other animals I have experience with. For grower feed I have a choice between an organic grower feed from a company known for crappy grain. You can tell when a horse gets their grain because it's coat looks scruffy. My other choice for grower is a local company known for good quality grains. Horses look amazing on their grains. Their grower is not organic but I use it anyway. When we switch to layer feed there is another company that makes an organic layer locally. I plan on buying that as I have only heard good things.
