It has me perplexed. It’s Kalmbach feed, available in non- GMO. Both 16 and 17%. I’m using 17%. Ingredients seem to be the same.
Would that be these?

I would expect one to be "organic" or "with special added ingredients" or "with pictures of chickens on the bag" or "no corn" or "no soy" or some other difference to make customers think it's better (along with a difference in price.)
Yup, that's what it is. The 17% is a special feed that probably costs more.
When I read the description, I see:
"Our #1 best-selling all natural layer feed!"
"Contains YolkProud™ – all-natural ingredients added to promote vibrant egg yolks"
"Contains LifeGuard®, a proprietary blend of prebiotics, probiotics, essential oils, and enzymes that support digestive, immune and health function."
Also, the ingredients list of the 17% feed is more specific in a few areas (like "corn" instead of "plant products," or "soybean meal" instead of "plant protein products.") So the feed may be more consistent from one batch to the next, rather than having the formula change according to which grain is cheaper this month.
So they've got the 16% ("Formulated for the maximum production of nutritious, strong-shelled eggs") for the no-nonsense people who want the cheapest feed in the lineup.
And they've got the 17% for the people who want to buy a special, better food for their chickens.
If I were buying, I'd buy the 17% if the price was the same or pretty close, but I'd buy the 16% if it was much cheaper.
