I usually try to buy them organic or non gmo, but it comes in tiny bags and it's so dang expensive... our local feed store sells this and the bag claims to be "all natural" but I dunno...
It's pretty much the same as any other conventional feed. The words you can't pronounce in the ingredient list are stabilized vitamins. Non-stabilized will quickly deteriorate. All natural, has no meaning in the US. It's just a term they use to make it seem healthier. Your chickens will do fine on it. However, it's not organic, soy free or GMO free. You need to find a source of 50 # bags of organic but even those are pricey. Perhaps you could talk your feed store into carrying it.
Its okay feed. There are no specialty ingredients such as probiotics, chelated minerals, yeast wall components, etc. that are helpful in maintaining the health and productivity of the hen.
