That's because it's a crumble or small pellet of pulverized ingredients, rather than a mix of whole or cracked seeds and other items. The value of this type of feed is that every mouthful has basically the same ingredients, so there's no picking out the grain and leaving the vitamin and mineral additives. Most of these sorts of feeds are fairly palatable to animals, and some even have taste enhancers added.
The problem I see with this particular feed is that the ingredient list is not specific: "grain products," "plant protein products," and "animal protein products" are the first three "ingredients." That's a cop-out, as it lets the manufacturer substitute within that category of foodstuff according to what's cheapest at the time. I know that commercial animal feed manufacture is a business, and I have no problem with a business making a decent profit - but not when it involves this sort of sleight-of-hand. Tell us exactly what's in the feed we're buying for the animals who feed us!
BTW, I buy a commercial layer ration that contains a mixture of readily identifiable cracked corn, field peas, oats, etc. as well as a powdery base. To make sure the chickens don't leave the added vits and mins, I drizzle a little vegetable oil over the top of the bowl and mix it in really well to make sure the powder sticks to the grains. There's very little left in the bottom of the bowl this way.
